Update: Not going to happen.
I give the poor little Honda 2000 credit, second try it fired up the compressor for 5 seconds but didn't have enough watts at these temps.
Tested at 120.2 degrees in the shade, TT in the sun all day with AC set at 80, removed shore power and ran E2000i on high. I even put in low fan for an extra few watt savings. Compressor cycled back on but couldn't handle it. At 100 degrees it could, but the extra 20 degrees made a big difference, both higher head pressure and lower hp. Just needed about 200-300 more watts at these temps.....or a hybrid inverter charger.
The gas was about a year old, but I doubt it made a difference in a sealed metal can.
On shore power the interior was holding 82 inside with a 58 output of the AC.
Of course I didn't start this till it was 96 inside and 105 outside, lol.
