The Dometic 3, 4, & 5 cubic foot RV refrigerators are very efficient as long as the cooling unit boiler is not allowed to overheat. The problem with these refrigerators is that they are mostly found in slide-in campers, class-b, and other everyday driver type RV conversions. As a result there is a high failure rate due to off-level use and other factors associated with everyday driving that destroys the cooling unit.
