APU's Next generation

.1 gallons a hour??? I didn't think any of them claimed to be that efficient. I have seen some claiming .2 and hour and talking to drivers that keep good fuel records before and after it seams more like .3 to .4 and hour is a more realistic. Not to bash you or anything but I also think the electronic motors use less than a gallon at idle also, but I could be wrong.

 

I understand that I also run a fridge and my batteries will last more than 10 hours on a charge and start the truck just fine. I have nothing against APU's I just will not spend the money to purchases one at there current price when I can come up with a cheaper alternative. I also will not run mine when the weather is nice it just seams to be wasting money, but that is just me and to each there own. The O/P said something about not wanting to spend alot of money and this is just what I did and do and it might not work for everyone.

 

My first backwoods APU in 1998 was a 4kw Coleman generator and a 5k walmart window unit that I cut and pasted into my 42 inch flat top sleeper. I used 5 gallons every 24 hours to keep cool in temps as high as 117 degrees. Now in my condo, I use a Honeywell I-2000, which is a 2kw generator and a 6500 btu walmart window a/c, and it uses 3 gal ever 24 hours of run time. So yes, you can be very comfortable on 0.125 gallons an hour.

My tractor uses .7 gallons on hour when idling, so I can run my backwoods setup for 5.5 hours, for the same amout of fuel the truck uses in 1 hour. Plus I can replace the generator and a/c for less than $500. For the $8500 some want for a APU, I'd buy myself a used 96 inch custom sleeper with shower, stove and bathroom and still cool it with my backwoods APU.
