Problem after Problem with new RV

Welcome to the club. May not be the case in your situation but we had a leak from the fridge caused by the drain for the defrost tray inside the fridge being stopped up. It is in the outside compartment and terminates in a small tray that defrost water is supposed to evaporate from. The hose has a plug with holes that I suppose is to prevent insects from crawling in but can stop up easily. With our new RV, it pissed my wife off but I resigned myself to fixing all the little stuff myself. Dropping it off at the dealer with a laundry list (which you WILL have) only insures you are going to be without your new toy for a longer time. Yeah, build quality sucks but most components are pretty well made and once you get past the crappy assembly, all will be good. You will want to get a tube of both the levelling and non levelling type of Dicor sealant to have on hand to stop leaks. If that fridge vent is really bad, I'd insist on a painted to match replacement. I'd suspect a really bad blowing storm could cause water to get in through the vents. I would not put any sealer on them. They would still have the vent holes and sealed you wouldn't be able to take them off easily.
