Why switch to a Residential Refrig, thinking out loud !!

I switched to a residential because the refrigerator is 38 degrees and the freezer 2 below when it is 40 outside and when it is 110 outside. The No-cold fire threat was not my incentive because if the coach burned to the ground insurance would have given me what I paid for it. Beats being 60 grand upside down. My feelings were burn baby burn as long as we ain't in it.
