Oh I agree, I just disagreed with the premise it's more efficient to run the generator than use the dash air. I've certainly driven many days that the dash air just doesn't do enough to make it comfortable.

Ive got the 10k diesel and it burn 1/2gal per hour (per the manual).

My cousin did not like having to run his generator on the road to keep the motorhome cool. I told him about several of my customers that had installed a bar and curtains behind the drivers and copilots seats. He did this and says now they have to turn the dash AC down when traveling in Georgia and Florida.

I know I contributed to this, but the issue isn't what it takes to cool the RV but the OP's issue of the gennie turning off while driving.

Be careful!!! Mine was doing that and caught fire!! They did not properly route or insulate wires from generator. Almost blew the whole motorhome up. I am traumatized.

Ditto on the oil comment. Most, if not all, of these gensets have a oil pressure switch that will shut the genset off if it notices even a momentary drop in oil pressure. This drop may come from a lack of oil, or from oil thining due to heat. THis switch may be bad, but do make sure your oil is topped off, not just in the zone but at the full mark. This will help prevent oil starvation due to acceleration (oil sloshing in the pan as you corner, speed up or stop).

So at 60 mph and $3/gal, it costs you $1.50 to go 60 miles, or about 2.5 cents per mile (cpm) to run your genset to cool the motorhome.

Sombody else said it cost them about 1/2 mpg to run their dash air. Lets say he went from 10 to 9.5 mpg, same 60 mph and $3/gal. At 10mpg he went 10 miles for 3 bux, costing 30 cpm. At 9.5 mpg he cost 31.5789 cpm. So it cost him 1.5789 cpm to run his dash air. Same cool air for half the price of running the genset, and he's not adding hours to the genset, incurring mx costs.

I'd run the dash air as long as the engine could do it. If you're in hills and power and heat are a concern, run the genset.

I was having the same problem on an older coach. Spoke to an Onan rep and he said to add oil to the very top of the dipstick. Didn't have a problem with the gen shutting off while driving after that.

One thing I always suspect when I read of a generator that runs fine when parked but cuts out when moving is the fuel cap/fuel tank venting.

If the shut down error is "Fuel" then it is possible the tank is not properly vented, as vacuum in the tank increases from the tremendous amount the main engine is sucking it is possible the generator can not suck enough fuel out of the tank any more.

However that is but one cause.. Clearly there are others. Most all fuel related.

OP, we just picked up our 2015 Forest River and the genny had a bad fuel pump. It would run for about 30 mins, whether parked or driving down the road, before it died. Dealer replaced it. Have you tried running your genny while parked to see if the problem only occurs while driving?

saronagrl · 08-05-2015, 10:39 PM

Bought it back to Cummins they replaced the fuel pump and carbarater. So far its been working good.

stevechris · 08-06-2015, 02:55 PM

I just found out my generator has an altimeter adjustment on it. Were you above 3000 ft if so check to see if your generator has an altimeter adjustment. Also, I just replaced my fuel pump because my generator would not start even thou I had over 1/4 tank of fuel. After I replaced the fuel pump I still was not getting fuel to the generator. I then filled my tank. Low and behold my generator started I guess I didn't need to replace my fuel pump.

I have a 02 HR Endeavor. Gas. 50 amp Onan. First time we had it on the road running the AC, it kept quitting. It would restart after a little while, but would only run a few minutes. I suspected it was shutting down on high temp. I noticed the the PO had installed a couple of bungee cords to hold the cover tightly in place. I had not been using them. There was a note on the cover that it had to be in place for proper cooling. I installed the door and used the bungee cords. End of problem. Drove several hours with roof air running strong.
