Fridge Question

I wouldn't wish fridge replacement on anyone but newbie or not there are just some things about RVs every owner has to understand, adequate leveling of a gas absorption fridge being one of those "things". Unfortunately the OP may have already caused some damage but also as the new owner of a used rig he also wouldn't have any idea whether the previous owner treated that fridge properly either. Hopefully this fridge hasn't suffered excessive blockage of the cooling unit but the fact the OP says it's not cooling as well as it should is a pretty good indication his fridge cooling unit may be partially blocked.
