What I am thinking, if it would work, is to get a stand alone room air conditioner, an AC inverter and maybe a little larger alternator.
The Air Conditioner pulls 880 watts and 8 amps, cools 200 sq. feet. The invertor is 1000 watt and then just for a little over kill bump up to a 100 amp alternator. I may also consider a different battery. (? not sure ?)
I have a little Honda 1000 watt generator for camping as well.
I could use the invertor for the AC going down the road and the gen for when parked.
The Air conditioner is a little over $300.00. Invertors are about $100.00. And I need to buy an alternator and battery anyway.
I was going to put in a regular automotive AC (Vintage, Southern, Nostalgic, etc.) but not only are they more expensive but, a bit of a pain to put in.
So what do you think?? Is this doable or am i barking up the wrong tree?
