I have a NTM 1982 Palomino Shetland. Super cute and in pretty good shape, but one big problem. The lift arms are fully extended, but the roof is about 1/2" too low for me to get the door in place. (Probably isn't helping that when I pull out the double bunk on the tongue end the box of the trailer spreads so that the door gaps and pops open. I read a really long thread on here explaining how the weight of the bed pushing down on the front of the box makes the wall with the door opening spread. The old ice chest box that used to be by the door has been removed and I imagine that provided some structural support that is missing now. This door spreading when the bunk is out seems to be a fairly common problem.) But the bigger problem is that the door will not go in at all because of the height. Just 1/2" higher and no problem. Don't know what to do. Am considering just making a mesh and canvas door covering and putting up a bag awning to keep out the rain -- I want an awning anyway. But do I need a door frame for structural support? Anyone had this problem? Suggestions?
