Has anyone ever installed a turbokool on a fwc or atc? They are "only" 16 lbs, and fit any 14x14 vent, will run indefinitely with a panel. As I am still a poser ( still waiting for the perfect used fwc to pop up, yuk yuk) I have no idea if lifting another 16 lbs is possible without a lift assist device.

There are also solarchill 12v swamp "vehicoolers". Way back in the day I had a small solar chill which I used while shell camping in the back of my 89 yota in Utah. I found I got too cold with it blowing on me, sold it to a friend and went with a fan instead.

In europe Waeco sells a 800 watt 18 kg rooftop ac that runs off 24v. Obviously one would still need a generator, but it has to be asked why don't they sell these stateside? Because yanks only want the biggest and bestest, no matter how inefficient.
