RE: AISIN or 68RFE on new Ram 3500

One big difference I've noticed is my 2015 with the AISIN tends to hunt gears a whole lot, much more than the 68RFE I had previously. You pretty much have to manually select gears when towing. On the plus side, shifts are noticeably more firm and it just feels more solid all around. I haven't got the mileage or use to determine actual durability in any way yet. First and second forward gears are nice and low but, it's a little tall in reverse which can make the tight spots where you're backing uphill kind of tough. Keep in mind my truck is SRW so it's geared a fair bit taller than the DRW versions.

RE: Ram integrated brake control

Regarding OtrFuns question regarding his multimeter readings, they're pretty much what I would expect to see. When it comes to AC, or pulsed dc, most meters don't display peak, or peak to peak voltage but instead display and "average" value (Oversimplified I know). The IBC uses Pulse width modulation to vary voltage, which has the same effect with simple circuits like electromagnets as what you would get with more traditional analog control. It's cheaper and easier to do with solid state devices especially because of heat generation type issues. With the Ram IBC the voltage is either 12vdc or 0, and the current varies in the same way. However, the effective current based on pulse frequency, load filtering effects etc. ends providing the same effects as what you would get with steady voltage/current output type circuits. Bottom line, while I carry a little pocket scope in my truck toolbox, and prefer to use it for circuits like this, the behavior of the circuits I've tested on my truck with my multimeter have given me the same results as I calculate I would get based on the scope. Finally, if your truck is setup like mine with 2 seven pin connectors you can easily see what sort of signal you're sending to the brakes by building a harness to run up to the cab of the truck through the rear slide window. I built one, hooked it to the bumper trailer connector plug while my 5er was hooked to the bed and looked at what sort of voltage was being sent to the trailer real-time. (Current would be a little harder to measure while driving) I never saw the voltage increase close to 12vdc even when traveling 45mph. I only tried a couple of times as hitting the brakes hard with the trailer on the back isn't all that fun, and not necessarily good for the equipment.

RE: Ram integrated brake control

Five pages of discussion about brake controllers (defective or otherwise) with no mention of voltage/current readings from realworld rigs? Maybe I missed it. My two cents: If your brake controller is capable of producing 12v and 300ma (per brake assembly) then it's designed to work safely with the vast majority of trailer brakes. Anything less correspondingly reduces the number of trailers it can safely stop. If 12v and 300ma (per brake) doesn't stop your rig satisfactorily, don't blame your brake controller, blame your wiring or brake mechanicals. On the flipside, just because your Ram IBC "works great" doesn't necessarily mean it's capable of producing 12v and 300ma (per brake), it just means your Ram IBC's voltage/current output is probably a good match with your trailer (which may need considerably less than 12v and 300ma per brake to brake properly). For Dexter axles, 7 inch brakes draw 2.5 amps at 12vdc in normal operation. The bigger brakes, especially the 2 X 12's we're talking about for the larger trailers need 3 amps each for max braking. 12 amps total for a 4 brake system. Normally you'd obviously need a little less than max current as you don't max your brakes out every time you stop. It would be nice to do so if necessary though. It's a pity Chrysler diasagrees.

RE: Ram integrated brake control

I'm no electrician, but it would be interesting to see what the output at the 7 prong connector was on the trucks that have problems vs those that don't. Maybe a few of you could get some voltage/amperage readings and compare? To look at the output, you need an oscilloscope or high end multimeter that will measure duty cycle, or pulse width of the pulse width modulated output of the IBC. They max out at a pulse width of approximately 67 percent, which results in approximately 2/3rd of the current flow the Prodigy brake controller will output. Supposedly you can get more output at speed above 30 mph but I haven't seen that on mine with max braking even above 45mph. You probably won't notice the problem unless you have to get on the brakes somewhat hard. I've towed a triple axle rig, 8k bumper pull, and my bighorn, and none of them would lock up the brakes with my 2015 no matter what the setting, all of them would lock up with other trucks, or after market controllers.

RE: Ram integrated brake control

One of the easiest things you can do to see what is going on is have a friend with a hitch equipped truck hook your rig up to their truck and see what happens. I hooked up to my neighbors ford and the trailer brakes worked great. With my truck using the factory IBC they're all but worthless. I don't personally know anyone happy with the newer RAM IBC, but unfortunately, Chrysler doesn't seem to be willing to address the issue.

RE: 1/0 lugs with hydraulic crimper

It would be interesting to see what sort of crimp was used for the testing in Trojans white paper. I've seen an awful lot of data/testing showing just the opposite over the years. In the aviation industry we use solder type connections quite often for low current applications, and in fact have to re-certify on soldering on a regular basis to include having your joints checked under a microscope. High current connections however are always crimped. A lot of engineering work goes into determining what sort of connectors to use for different types of circuits, and these are continually being re-addressed based on MTBF data and incidents investigations following failures. That said, a proper crimp results in cold welding and a gas tight connection that will result in a quality low resistance bond. Most of the shade tree mechanic stuff I see involves a crimp with pliers, or one of those hammer type crimpers resulting in questionable bonds. Resistance, corrosion, and eventual failure are pretty much to be expected in a crimp improperly done.

RE: Trailer Brakes - How hot is TOO hot?

Your trailer dry weight is pretty close to what I have, and I would expect given your axles you have pretty much the same 12X2 brakes. My experience even with steep mountain driving is that the engine brake on my Ram Keeps me from using all that much braking and thus the brakes don't get very hot. That said, Hot is kind of a relative term so if you get an IR gun and get actual temps folks might be able to help out more, but personally I would get professional help in checking things out if I wasn't sure being as how properly functioning brakes are such importance safety wise. As others have mentioned, you have t break in your brakes before they work effectively. Finally, as BossHog mentioned, your Ram truck brake controller is seriously flawed in that it doesn't apply full braking power to your trailer. My brakes draw approximately 12.3 amps when hooked straight to battery voltage, and max out at approximately 7 amps from my IBC when not moving. I've only checked the Pulse width, or duty cycle when driving rather than measuring current so I can't confirm current, but voltage pulse width maxes out at 67 percent on my truck, even when traveling well over 30 mph, so I question whether the truck ever will apply full braking. So far, Chryslers refusal to admit to, or deal with the issue in any way has convinced me that there will never be another Chrysler product in my future.

RE: Anderson Ultimate and aluminum truck bed compatibility

Wow, the misinformation flying around on this thread are pretty bad. To Clarify, first, I've used an Andersen ultimate hitch on a 3500 Ram for coming up on one year now, a little over 5000 miles of towing, about 1k of that with a 17k plus triple axle rig, the other 4k with my smaller bighorn GVWR of 15.5k. I'm an engineering tech, almost 40 years as and aircraft mechanic, 20 of those in heavy crash repair, service life extension modifications and failure analysis. As mentioned, I use and Andersen ultimate, haven't complained about it, but try to keep the discussions honest. Once again, the Andersen Ultimate hitch doesn't transfer the weight to the gooseneck ball. The square base tube base is made up of a tube within a tube, and doesn't have a socket per say and doesn't ride on top of the ball, it goes over it, whereupon you put in a pin that goes under the ball. You then tighten a bolt on top of the square tube that pulls the smaller tube insert upward pulling the base of the hitch down firmly into the bed of the truck. Any force put on the ball is pulling on it in order to pull the base of the hitch down. Once the hitch is anchored down on the bed you then tighten to bolts on the forward part of the tube assembly that takes out any play or slack out of the dual tube assembly. This setup does a great job of keeping the hitch assembly firmly mounted to the bed of the truck. The design distributes the weight over a fairly large footprint onto the bed of the truck. Whether you feel carrying the weight of the load on the bed of the truck or not is a good idea, that's valid question, and there are probably enough users around to make the decision fact based. My hitch was starting to cause some noticeable indentation on my truck bed, so I made myself some spacers to distribute the weight a little better. Finally you see comparisons to the earlier version of the B&W hitch, but that isn't necessarily a good comparison because the way the bases distribute the load is a fair bit different.

RE: Anderson Ultimate and aluminum truck bed compatibility

Again, all of the weight is carried by the truck bed itself. When you install the pin that holds the hitch to the ball, you then torque the bolt on the top of the square portion of Andersen hitch. This pulls the whole hitch down firmly on the bed of the truck. The instructions now have you do this with the weight of the trailer on the hitch so it's actually held down pretty solidly to the truck bed. With 3000 plus pounds of pin weight my normal trailer loading has results in the bed of my truck having completely flat indents in the spray in bedliner of my truck where the hitch lies.

RE: Anderson Ultimate and aluminum truck bed compatibility

As Me-Again pointed out, all of the weight is carried by the bed of the truck when using the Andersen Ultimate hitch. I'd have to look in depth at the truck bed to see if I thought it would hold up to the weight and potential flexing. Personally I probably wouldn't use one with 5er of any size if I had an aluminum bed. That said, I would avoid the aluminum bed if possible as I use my bed for a lot of stuff, much of which would seriously scratch and gouge aluminum.

RE: brake controller output

Whether the controller is controlling amps or volts is an interesting question. I always assumed it was volts. Amps is actually what determines the strength of the magnetic field but it should be directly proportional to amps. I haven't ever checked a Ford, but my GM, Ram, and Prodigy controllers I've owned have actually controlled both voltage and current in a crude sort of way. What they actually do is send the full voltage from the Circuit breaker to the brake solenoids, but do so by switching on and off really rapidly. (Pulse Width Modulation) the frequency, or number of pulses per second stays the same, but the duration of how much of how much time during each pulse power is switched on varies (Duty cycle). Some millimeters, and all oscilloscopes that I know of can measure this for you, and with a scope you can see a graphical representation of the voltage waveform which is handy for visualizing what's going on. (Yes, I'm one of those guys who carries a pocket scope in the tool box of my truck) If you have a newer RAM truck, the duty cycle maxes out at 65 to 66 percent, with Chrysler saying it goes up with speed. (My own testing says otherwise) My trailer brakes draw about 12.3 amps when connected straight to a battery, but max out at approximately 6.5 to 6.8 with the IBC on my truck. I'm still working with Chrysler to try to resolve this, but it causes inadequate braking to put it mildly. To add insult to injury my trailer brakes work fantastic if towed by my neighbors ford, or with a cheap aftermarket brake controller. How embarrassing ;-}

RE: Air Conditioner Test

Delta T of 15 to 20 degrees isn't an old wives tale, it's a well known design parameter of most residential type AC units used in Homes, RVs and Autos. It's not an indication of what the system is capable of but instead an airflow to Temperature relationships that results in maximum performance in the conditions the unit is designed to operate in. An HVAC mechanic will have access to technical data detailing the optimal temp changes to expect from the particular system being looked at, and take troubleshooting from there. Changes of more than 20 degrees in most systems and you start looking into the possibility of the unit being low on refrigerant, or clogged filters or other issues that might be reducing airflow. Temp changes that are to low could again be again low refrigerant, either through causing icing, or low enough to reduce cooling etc. etc. As others have mentioned, your AC generally continually recycles the air within the home/rv and auto depending on setting. How effective it is at cooling that airspace is dependent on both temperature and volume of air processed. Designing the system to be the most efficient at doing that generally results in a system with an intake to output temperature differential across the cooling heat exchanger of approximately 20 degrees.

RE: No vent hood over propane stove

My microwave has a vent fan and sits above the stove, but it only runs if I have AC power. Not sure of the logic in that being as how I thought part of the reason to own an RV was to camp without hookups when desired. I wired in an inverter, but it stills seems like a dumb setup.
Searching_Ut 08/09/16 07:15pm Class C Motorhomes

My last 2 TT's were mostly DC powered for everything except the microwave and Air Conditioner so I only used a 400 Watt pure sine inverter in the bedroom primarily to power my ASV type bipap machine. It worked fine even if I chose to run the humidifier. It's a 28vdc machine and I never bothered to get a DC adapter for it as I already had the inverter. The Bipap I had prior to this one worked on 12vdc so I just direct plugged it into a DC plug I installed in the bedroom. I wired a 600 Watt Pure sine inverter into my current 5er auto transfer switched to power the whole trailer. I currently have to remember to turn off the circuit breaker for the DC converter before I turn the inverter on, but will wire in a relay to automatically isolate that circuit when it gets cool enough I feel like crawling into the equipment bay area. I also switch the fridge to gas and the water heater as well. My 600 watt inverter powers the TV's, microwave vent fan if needed, my powered recliners etc but isn't big enough for the microwave, AC, or any heating items bigger than our crock pot. It also powers my Bipap through the night no problems.

RE: Washington mid October

DW is really interested in Gig Harbor as we've been researching it. Don't know why we haven't explored this area much being as how we generally travel an average of 7k miles a year. We've taken two cruises out of Seattle, and flown in the day prior so we could hit the market etc. and drove through once when we took a week heading up into Canada for another Alaskan cruise (Cruise ships are really just big RV's) Like all to many other areas though, never really explored in depth. Thanks again for all the suggestions folks. DW is even interested in the reactor site which surprised me being as how I had to drag her kicking and screaming to hit places like reactor 1 at INEL, or the Thiokol site up near promitory point. So far the only recommended places we've actually been to are the ones in the Burley area being as how we hit that area multiple times in any give year. We get a lot of 3 day weekends and explore southern Idaho a great deal.

RE: Ran batts down so I could watch the Solar charge them up

You can check the output of the solar without charging the batteries, but that takes some of the fun out of it. If you don't see how much charge you can get into the batteries, and how long it takes to do it it's kind of like cooking your baby back ribs in oven rather than outside in the smoker. It's all about enjoying the journey, even if it's out in the driveway.

RE: Ran batts down so I could watch the Solar charge them up

Did you note the results? If so, how about telling us about them? I have to say, you're weird, bizarre, possibly mental etc.... That said, I did the same thing when I installed my panels earlier this year. Worse yet, I wasn't even camping, just parked out front of the house, ran them down to 50 percent according to my trimetric overnight, then went out at the crack of dawn t0 see what sort of output I got prior to sunrise and verify battery state of charge, then periodically checked throughout the day as the sun rose. I'm hoping to have my RV pad poured and should probably take some pictures and show my install as a contribution for whatever it's worth to the forum. As for what I recall from the first day. Mountains to the east, so it gets fairly light out prior to the sun breaking over the mountains. Solar output reached about 1.5 amps prior to the sun hitting panels direct. (Battery switch off so all pwr to batteries) With 5 100 watt panels on roof, parallel wiring and only tilt being curvature of roof the current jumped up to 7 amps when sun broke over the mountains. Hit 34 amps by 10am maxed out at 25.2 then dropped down around 24 amps until it started dropping fairly quickly until the charger dropped out of absorb when batteries hit 85 percent according to the trimetric. Voltage dropped from 14.8 to 13.2 and current down to around 8 amps slowly falling off from that as I recall. I hit 100 percent on around 3pm (3 Group 24 batteries, started at 49 percent state of charge according to trimetric.) Temperature at Sunrise was approx. 68 degrees climbing up to 91.

RE: Tire pressure, question on increase.

My normal change in the summer is from 110psi to somewhere in the mid 120 range, with a split of 6 to 8 PSI difference between sun and shade side of trailer. Even with it just sitting there not moving I can get more than a 10percent increase from sunrise, to afternoon heat. My truck is the same.
