What kind of a/c do you have. I'll be in the market in the Spring. I need to be able to run it on 2000 watts. My furniture pad curtains hold the heat in there WELL. No need for insulation even.
Running a 8000BTU Soleus/KY 80/other names (around 300.00 new)...powered by the 2000 Honeywell. Built a framework around the unit (passenger seat removed) so it slides in and out of it's "sleeve" whenever I need it. Most of the time, you can just pull it straight out, and you have to, to clear enough space between the door and hose hookup vent. Custom fitting on end of hose rolls right up into the window with two fitted foam rubber pieces to fill the window gap. Hooks up in less than 5 minutes, generator and all.
There's enough hose to turn the unit 90 degrees and have it shoot right into the sleeping area. In Laredo it worked fine....but don't stray far from the direct cooling flow vent...and I didn't.
Hot as pistol when down there last summer.
May work a deal where the owner takes it. I'd turn right around this Spring and grab the same air unit, but probably go with the Yamaha generator, though the Honeywell runs great and powers the unit through all cycling....on energy save.
