One more thing you might want to check if you have an kitchen island. When we got our trailer I went around outside and sealed every crack or hole I could find which was not many. We then turned our attention to the inside and did the same. One of the largest openings inside was under the kitchen sink where the drain pipes and water lines came through the cabinet floor. I sealed that area with expanding foam. We had noticed when we first got our trailer that sometimes we would open the pass thru storage doors we would feel cool air but we had sealed every opening we could find including those in the storage areas. Couldn't figure it out.

About two weeks ago my wife pulled the plastic trash can out because something fell behind it and I saw her get the flashlight out and looking around that area. Seems the island has a raised floor under it and she spotted about a 8"X 8" opening under where I had sealed the pipes that dumps into the basement area under the floor. I bought another can of expanding foam and went to work sealing that area off and now we feel no cool air when the storage doors are open. We were loosing cool air through that opening into the area under the floor. So if you have an island with the trash can on one end of the sink pull your trash can and shine a flashlight around the floor under the sink cabinet and see if you find what I did. It was not a big opening but we were loosing cool air out of it.
