RE: Good truck for towing

Possibly make it work if you carefully watch every pound and don't pack heavy: 1500. Comfortable: 2500

RE: Ford V10

That engine makes its peak torque at 3,250 RPM. It makes peak HP at 4,750. To climb a hill in a hurry you need more HP. So, by staying below 4,000 RPM you are giving up HP that the engine could be making if it was spinning faster at 4,750. However, many people say the "best" RPM to pull a grade is at peak torque. At that RPM the engine is most efficient at hill climbing but not necessarily the fastest. So, take your pick, you can have speed with RPM or you can have efficiency and possibly cooler temps at peak torque but you can't have both.

RE: 350/3500 trucks, engine weight gas vs diesel

I never really off roaded that hard with my TC on my 2005 Chevy dually. I do take the truck off road to off the grid cabin sites for work. It's usually loaded up to about 10,000 or more pounds with tools, supplies, equipment, etc. I have no trouble going up steep hills in low range, thru the mud, or over rocks with it.

RE: Battery maintenance

Disconnect they will be fine for months. Or, you could install a solar panel to keep them topped off and provide some power when camping without hook ups.

RE: Life of AC?

When I solar my camper the AC unit was 15 years old. It still worked great. I would try a new breaker first, that will only cost you about $5 for the breaker and 10 minutes to change it. There's no way 3 to 5 years is a normal failure time frame.

RE: Solar controller float charge at 13.6

Look up the manufacturer's recommended float voltage range for your batteries. Compare that to what you controller is doing. Anything else is nothing but guessing.

RE: SRW vs DRW

It's just math. If your trailer is withing the payload capacity of the SRW then a dually isn't necessary. If you're talking about a better towing experience than the dually will almost always be more stable and handle better with just about any trailer. I've been towing all manner of trailers and equipment behind my dually for 15 years. I just hook it up and go. No sway bars, no WDH, just a ball. It always tows great.

RE: Switching from 12 volt to 6 volt batteries

When you connect batteries in series you add the voltages but not the AH capacity. 2 of those batteries will only give you 225 Ah at 12v. It's a significant upgrade from what you have for sure. If it were me I'd go with standard wet cell golf cart batteries. They will be less expensive but you will have to keep tabs on the water levels.

RE: Inverter

First of all, a 30 amp outlet IS a 110 outlet. Actual, they are all 120 volts as that has been the standard for decades. For some reason the old 110 / 220 volt lingo won't die. So no, the outlet choice didn't make the wire get hot. Are you running the AC thru the inverter's transfer switch? It's possible that due to all the voltage drop in the small wire feeding whatever outlet you were plugged into that the voltage at the inverter was below it's lower limit. Therefore it may not have actually connected to the shore power and was instead power your air conditioner from the battery. If that's what happened then plugging into a 30A RV outlet should cure the problem because of the theoretically larger wiring and thus less voltage drop.

RE: Adding on board Generator

Since you have a diesel rig you need to get a diesel generator. Cummins/Onan is the brand you want. Stay away from Generac. Those are basically the only two choices.

RE: Battery replacements in 2013 Chevy Silverado 2500 Diesel

Every Advance, Auto Zone, and even the little one man shop battery places install batteries for free. Granted, they must be charging enough for the batteries to cover their efforts but have you checked any of these places? At 7 years I would replace both of them too. They are both their under the hood. It's not a complex job but you have to be very careful you don't short anything out.

RE: Solar and VSR relays

I will respectfully disagree with the last poster. I don't think it's strange at all. In fact, I have basically the same set up on my truck and TC. When parked at a camp ground frequent opening of the truck doors triggers the dome lights. Do does using the truck's radio or in my case ham radios that were wired to the truck. I liked the fact that my camper converter or solar panels were keeping my starting batteries topped off. The camper can't drain the starting battery as you fear. When the voltage gets below around 13 volts the voltage sensing relay disconnects the batteries. My starting batteries and RV batteries were both flooded lead acid, same chemistry. While technically not an ideal combination to charge in parallel the charging requirements are basically the same. I had no problems in many years.

RE: dry docking and charging

What gauge are you looking at? The little Full - 2/3 - 1/3 red light gauge? If so, that thing is useless. It's looking only at voltage. The voltage is high anytime the converter/charger is operating. An actual battery gauge that uses a shunt like those made by Tri-metric, Magnum, and others will give you 0 - 100% reading of what's in the batteries. Some RV converter/chargers are notoriously bad. Most people don't really do much camping off the grid thus they don't need a good charger thus the RV builders don't install a good one to save cost. Don't use the 12v output from your generator. It is also useless. Plug the RV into the generator just like plugging into an outlet and let the build in converter/charger do it's job no matter how poor it may be.

RE: Is anyone towing with a Chevy/GMC 1/2 ton 3.0L Diesel?

You rarely pull at an RPM higher than 2500? You must have a really light trailer, live where there are no mountains, or just like lugging the engine to death. I was pulling about 5000 lbs through the mountains of TN in tow/haul mode with the cruise set on 60 and let the 8 speed do the work. It would occasionally drop 5th gear at 2700 rpm. Most of the time it was in 6th gear at 2200 rpm. That's remarkable. When I've got 6,500 pounds behind my 2009 Suburban with the 6.0L I'm usually down to 4th gear or even 3rd to maintain interstate speeds on the grades here in VA and WV.

RE: Honda 2200i or Honda 2200i Companion?

The companion has 1 "normal" 120v 20A outlet and 1 120v 30A twistlock outlet. You obviously can't pull 30 amps from it without having 2 generators in parallel. The "regular" Honda doesn't have the twistlock; instead it has a duplex 120v 20A outlet. Either will work if you don't need to plug in more than 1 thing.

RE: Carseat Advice for Quad Cab Truck

If you want to disable the passenger side air bag just pull the fuse. Assuming that your truck has separate fuses for driver side and passenger side air bags. Some do, some don't in my experience.

RE: Mounting a truck camper on a chassis truck.

I think if you look really closely that 1160 won't fit on the Knapheide bed. I never found any full size camper that would fit on any standard utility body without modification. I would guess, if nothing else, the little angled wing walls on the camper would interfere with the outsides of the utility body. Even if they don't and the body slides between the camper wall and the wing wall you won't be able to get the rear utility body door open. Then, what do you do about tie downs?

RE: Ac question

I've run my AC unit a lot when using a 30 to 15 adapter and plugged into a 20A circuit. Air conditioning unit, refrigerator on AC, and the converter at the same time never caused a problem. The AC unit pulled about 7 amps running, ref was about 3 amps, converter varies but never that much.

RE: Power cuts out when pump runs (on DC)

Are you sure your batteries are good. Your voltage measurments are useless because your solar charger is holding the voltage up. Batteries do not have a resting voltage of 14.2, that is under charge of some kind. In fact, 12.8 is a little high for resting voltage. A fully charged 12 volt battery at "rest" will only read 12.7 volts. With a little load it will always be below 12.7 volts if there is no charging source present. Unhook you solar charger, unplug from shore power, then measure your voltage with and without a load.
