I posted about the 2013 livinlite 10 truck camper being too hot last year, and it still is, but there is hope. The Coleman Mach air conditioner was shutting down the compressor early, so the inside of the camper was hard to keep cool. So I checked out a great video on YouTube. It shows how to turn down the thermostat adjustment screw, to keep the compressor on for longer. Just do a search on Coleman Mach air conditioner thermostat adjustment, and it really is a diy. I figured out where the side of the thermostat with the adjustment screw was, and made a 1" square hole, and did the adjustment without taking everything apart. Priceless
