RE: Change Differential Gears to new Ratio?

My calculations were based on routes I've traveled before multiple times in both directions with gas receipts.

RE: Buying a B in Canada

Sorry you found it not useful. I was trying to be helpful, and I've toured the facility. But since I'm useless to you, I'll stop now. Gee thanks. Hopefully others will have some info that might actually be of some use.

RE: Change Differential Gears to new Ratio?

Then, why did I see a 1 mpg improvement when I went to larger taller tires? I use the cruise control when at all possible and I'm a slow driver. It is proven that operating at low rpm with foot deep into the pedal produces lower fuel economy, than operating at higher rpm with less thottle, when the engine is under load.

RE: A/C Question

twenty amp female outlets will always accept a 15 amp male plug. Doug you are correct it's a 50 amp to 15 dogbone pig tail. As far as the outlet I used a 20amp breaker with yellow 12-2 directly to a 20amp gfi outlet. But yes you are right it it must be 15amp I guess since it allows the 15amp dog bone to connect to it???? :h

RE: Change Differential Gears to new Ratio?

So why would the throttle be farther open at lower RPM?

RE: Travel with fridge on

Hi, Before I had the ARP protection device I shut down my fridge or drove in circles in the parking lot until I found a level spot. Now I still try for level--but I'm far less concerned. And yes, damage can happen in 15 minutes. Replacement cost for my fridge is $3000.00

Well there is a B factory in Saskatoon, Sk.

RE: Change Differential Gears to new Ratio?

Then how come I use less throttle at 50 mph than at 60 mph? (and way less fuel) Lower engine speed equals larger throttle opening, which effectively negates any fuel savings.

RE: acceptance charging rate AGM batteries

Naio, Most of the time I get little charging if any from the alternator. The voltage of the jars is higher than the starter battery--so my solar system sends current to the engine. I'm set up with dual charging paths with #8 wire. My alternator is the stock 130 amp--so there is little or no risk of the chassis sending too much to the battery bank. My maximum safe charging rate is 108 amps--far more than the alternator can possibly send after it supplies 30 amps to the running of the engine, etc. If I run the water heater--then I get quite a bit of charge going to the "house". I have seen 70 amps (meter tops out at 70) I do plan on getting an AGM starter battery.

RE: Dometic refrigerator wire shelf replacement

Hi, I scrapped mine and then used rust paint on them. They look better than new. I created thin plastic liners for them that should help with the inevitable spills.

RE: acceptance charging rate AGM batteries

Hi pnichols, I think you are wrong. These batteries are designed to be permanently on float--and then when the power fails tolerate large loads. I have no idea how many jars they put in a cell phone tower. Of course low and slow probably will not work on the special AGM batteries in your rig.

RE: acceptance charging rate AGM batteries

Hi BFL13, Your posts are always stimulating. I'm going to ramble now. My maximum charging rate is 27 amps per jar i.e. 108 over all. I've only seen that rate once when boondocking via generator charging. I had deliberately run a total load of 1000 watts for 4 hours. I did see it in June when it was extremely hot and I had "forced" the load support into voltage support mode and was drawing 64 amps from the battery bank. I get about 17 amps at solar noon when the battery bank is hungry. I'm back to blacktop camping because it is not too hot during the day and not too cold at night. (high of 26 (79 f) today and a low of 14 c (57 F)) I'm using 3 amps and the solar is providing 7.9 amps @ 14.5 volts. The float light on the Blue Sky 3024 is flashing and I'm well under the 1% that Mex suggested is 100% state of charge. I'm really not used to generator charging. Another way to ask my question may be "At what percentage state of charge the acceptance rate of a surplus acid AGM reach 12.5 amps per 100 amp-hours of storage?" Since I have 556 amp hours, that would be 69.5 amps. So far, I've hardly ever seen that rate of charge, but I've also been a "power pole princess" since June. Forgive me for "thinking out loud".

RE: Change Differential Gears to new Ratio?

Hi, I put oversize tires on my E-450 class C. That had the effect of lowering the differential ratio. I gained about 1 mpg. It was not cheap. I did it for more ground clearance and better tire load capacity. I would do it again.

RE: acceptance charging rate AGM batteries

Hi Mex, I came to the conclusion that they are best treated as if they were sealed flooded batteries, that happen to not taper on charging quite so soon. My goal is 100% each and every day. With high ratio electrolyte telecom batteries, a more important point is to ensure they do not get or remain over-discharged. That's like 100-times more important than futile micromanaging C-rates.

RE: Sprinter motorhome boondocking

Hi dave, Thanks--but these are just ideas I've gleaned from various web sites--and my own personal experiences. The other essential for boondocking is lots and lots of power. I have a modest solar system and would encourage you to have 600 to 1000 watts, a large battery bank, and a large pure sine wave inverter. That will run everything including the roof air (but not very long on air). I have a much smaller inverter that I use for running my laptop computer--or sometimes a heating pad.

RE: A/C Question

Hi Outlets and plugs are rated to 75 C (167 f). I prefer to not go higher than 50 C (122 f). I use a "point and shoot" thermometer to check that out. I can limit the amperage I draw so I'll "dial it down" if I'm getting overheating.

RE: Sprinter motorhome boondocking

Paper plates and minimal water use. Take every opportunity to use bathrooms at public locations such as Walmart and gas stations. I don't drink water from the tank. I use 1 gallon jugs for all my potable water needs. Wipe down silverware with paper towels. Don't fill the sink with water for dish washing. I sanitize by using 1/8 cup of water and a frying pan with a tight fitting lid. For cooking I use a small George Foreman grill. That is cleaned with paper towels. I sanitize it with a web paper towel plugging it in until I hear the hiss of the steam. Then I wipe it clear of grease. Finally I plug it in again until it cycles to kill any bugs. I heat and cook in the microwave using paper towels to prevent spatters. For bathing I place a wet wash cloth in the microwave and use that for my ablutions. I rinse it out, and then sanitize it in the microwave. I should buy stock in a paper towel company!

RE: INVERTER SELECTION HELP?

400 watts is not going to run a microwave or a saw, and I'm doubtful about the shop vac. It is pure sine wave. It does accept ring terminals. It is on sale at Best Buy for $97.99 Wagan does not have a great reputation--but if you connect it directly to the battery bank it should run the fan and other small load items well.

RE: who dry camps with residential fridge?

Hi, Add 600 watts of solar, a 400 amp-hour battery bank and the residential fridge will run forever. My friend recently took a few days away from his 2016 Bounder with a residential fridge and ask me to monitor the voltage discharged on his batteries while gone. 18-24 hrs max without having to start the generator. For this reason Ive decided to repair my norcold when that day comes. Is that the norm?

RE: INVERTER SELECTION HELP?

Go Power or Samlex, 300 watt unit wired directly to the battery bank. Make sure what ever you buy will accept ring terminals.
