I'm sure it works fine but you need to keep something in mind. When it's above 90 or so outside there is nothing that's going to keep your whole truck cool. You would need a 100,000 btu unit to do that job. The real purpose of those APU's is so you can sleep comfortable so vents are usually placed so that they blow on you while you sleep.Originally Posted by pigrider

Steve what is your opinion on the battery powered apu?

I have a Rigmaster which is a 20,000 btu A/C but will not cool the cab down but will blow my socks off with cool air as I sleep which is really what you want.
I was in Texas once and I met 2 people who had APU's. It was 110 outside and they had the APU running with the A/C on, Idle Air hooked up and running and the truck running with the A/C on and it was still hot inside the truck. It was so hot I had to use my T-Shirt to hold onto my chrome door handle to open the door.
My guess with that battery powered A/C is that after 8 or 10 hours of use you would have to run the truck for 10 hours at least to recharge the batteries so if you were shut down for the weekend you would be out of luck.
