Just got of a 7 night camp in N.Ga over the 4th of July in a 2017 268rks. Had AC on all the time. Came with the 15k single unit. Temps were in the low-mid 90s every day. We found that if you open the direct vent at the AC unit but cooled the main cabin better during heat of day. We run everything full tilt when camping trying to make it break while under warranty (residential fridge, outside fridge, microwave, TV, lights, AC. No problems and this is our 4th camp. It is a lightweight build so can't manhandle the doors and stuff for sure...
