Hi pdeter
I bought the LUX heat only 2 wire thermostat. I have roof air conditioning.
Robot Check
also put mattress toppers on rear queen bed and the overhead bunk. replaced Seiki tv and separate dvd player with a 32" tv with dvd built in for extra over head storage. also covered the entry way with a piece of 3/4" plywood that stores behind the drivers seat to give the dog extra room when driving and at night.
