I have a 2013 keystone alpine 5th wheel that was purchased in Jan. everything was working fine until one day the freezer wasn't keeping things frozen. I thought maybe it was too full. I took everything out and noticed the back wall was all iced over. I was able to remove all the ice and everything went back to normal. It's been a few months and two days ago the freezer items were not frozen again but this time the fridge was getting really warm. It again had all the ice build up on the back wall. I've cleared it all out again and still no luck. I switched it to gas and the fridge will kick on and off. The fridge is on a slide with the two vents on the side. They appear to be good. I'm new to owning a trailer. Does anyone have any other suggestions for me. Thank you so much
