You could always rig up a bigger tank on the small generator. The small generator would be the way I would go - you'll just have to be sensitive to anyone camping right by you (get extension cords so you can run the generator far away). All those Honda generators are amazingly quite though.

Heck 3.8 Hours on .6 gallons? You only need 1.2 gallons to go all night.

For the air conditioners that I've been able to find numbers for, they are as noisy as the generator, 58-60 dB.

Thank you, very much.

I'm sure conservation is a major point here, for all the various systems.

This brings us back to another camping thread quite a while back.....
I found these tenting units interesting notwithstanding Jakes impression. I think then the AC unit could be integrated into the vehicle instead of the tent. Fire scares me. Take a look Three Dog Camping

The other thought is a popup tent unit with AC attached.

I'm interested in what you decide as a solution. Let us know Pete.
