I insulated mine (8X10) with reflextex A bubble wrap with foil . Two layers, cost about $50 and just stapled it to 1/2 x 3 wood strips screwed down the center. Installed a 5000 btu A/C unit in front wall. Kept the trailer at 70 degrees when it was 96 outside. Sleeps good too. I run the A/C unit with a Coleman 2000 watt generator. Will run all night on about 2 gallons gas. Very pleased with results and fairly cheap too.
