you didn't say what trailer you had and if you had other options . i know in the summer most of my overhead cabinets get warm.when we are in the trailer we generally keep the bread or rolls on the countertop.. i agree the cabinet beside the refrig. vent does get warm.
Sorry we have a rockwood 8314 ss 2008. We have only had it out in the winter months and are having this problem. We just purchaced the trailer and are still learning little tricks of the trade. Thanks for any info
