It may seem like a simple concept but you're still not hearing me. The amount of heat that box makes will be neglible compared to the thermal properties of an RV cabinet. Of course an "enclosure" traps heat but it's the amount that matters. Keeping your heater turned up 2 degrees will make your unit warmer than one in a cabinet in a cooler RV.
It's a real stretch to assume that's what caused the OP's unit to melt. Resistive connections (which were tight) or the relay contacts are more likely the culprit.
