idea: Boondock with A/C and a LIGHT TINY CHEAP GENERATOR

I want to do some dry camping where the afternoons get alittle too warm.
ReThinking the problem - why not bring a small window AC? Then I can bring a little 800 watt generator!

I don't really need the roof 13500btu air conditioner all day long.
So I don't need a heavy $1000.00+ 2500watt generator to run the TM roof AC.

My April 2010 Highways magazine had a $79.99 coupon at Harbor Freight for a 42lbs 800watt/900surge generator - so I bought one.
This should run a small $99-$199 5000btu-6500btu AC. (The units with remote control are worth the extra $, IMHO).
For example I found a 48lbs 6500btu AC on the internet with requirements of Input Power: 607 Watts (Amps: 5.0).
(Used window ACs can be found cheap at garage sales, craigslist and auctions.)
Alternate AC idea: Evaporative (swamp) cooler - needs water but doesn't take as much power. I hate them.IMHO.

Also bring 12v or 120v fan inside to move air and make it feel cooler inside.

Where to put the AC:

1. Outside on shelf or table made to hold at window height against screen. Or maybe hang with ropes over the roof.
2. Anyplace inside hanging the backend over the large shell gap.
3. Pull front bed in about 6" and set AC with backend hanging over the gap.
   • For 2 & 3 above:
   • Put cardboard or whatever over hind end of AC to seal top and sides.
   • Also cover extra gap with mattress/cardboard/whatever.
   • Put a small fan outside blowing up the AC outside coils to help cooling.
   • Remember there is a humidity drain in back.
4. Outside again but unlike #2&3 - duct the cold and return air into TM. For occasional use cardboard or plastic bags can make ducts.
5. Your ideas?
