$$$Roof or dash air$$$

Has anyone ever thought about the difference in $$$$ running your generator with roof air and refrigerator vs dash air while traveling. The best I could figure my 8000 onan only used about 0.5 gallon diesel running 2 basement air and a large refrigerator this is on a 40 ft Itasha with 400 hp and itís nice when you stop the full coach is cool. Just wonder what your thoughts might be.

I run our genset anytime it's hot with the AC running full blast. The dash air is nice but does not cool the entire coach.

You spend all this money on your rig and are too cheap to spend the money to be comfortable? I think not.

If the MH is moving it really doesn't matter. Most of the cost will be to propel the box with wheels down the road.
IMO if you only drive the MH 5k-10K per year the mpg doesn't matter either. It will amount to less than a 100 dollar per month difference.

I run what it takes to keep the coach at comfortable temperature. Most of the time the dash air is on, as temperature rises I start the generator. The cost is negligible.

In my case it is less expensive to use the Generator. My side radiator fan is run by a hydraulic motor and costs 1MPG in fuel economy because the dash air causes the fan to go into maximum speed. The generator running both roof ACs costs less than half of that. (and much more comfortable)


Have a nice day - Darrel

The dash air alone is OK to keep us cool while on the road but the MH gets too hot! We usually run the genny and both A/C's when we're an hour or so from our destination to cool down the MH. The Onan QD7500 burns between 1/2 and 1GPH.
