Older fridge cooling Better on 110 than propane

Ernie, where’s the refer’s top vent on your RV? Roof or sidewall?

If it’s in the sidewall, that’s essentially the same as a refer installed in a slideout.

Either way though, you should get the installers guide for your fridge, and compare the clearances, insulation, and air baffles with your install.
