I like the way you think but it's just not gonna happen and is my wife's biggest complaint while dry camping,no AC.

Most of the places we camp have hookup but when we do occasionally dry camp we choose our weekends wisely or head for higher elevations.

I highly doubt that your trailer is going to be able to carry the weight of the batteries!

If he were to go the Lithium route a 100Ah 12V weighs in at only 31 lbs. Your typical group 24 81Ah battery weighs in around 50 lbs.

When we are running cross country and end up staying the night where it is hot, we simply start up our $500 inverter generator and run the A/C. It burns less than $5 of gas to run it all night.

^^^ This is probably the only viable way to run AC all night while boondocking. The 12V 100ah batteries are lighter, but if my math is even close you still need 10 of them to run a 13.5K BTU AC all night. A decent inverter generator should be quiet enough so that you would not hear it over the AC.
