Ever since I bought my 2008 Elite horse trailer with living quarters I have had problems with the slider to access the door opener on the screen door; it continually jumps off track and has to be replaced. It still has the 2 little tabs that hold it in but it is just not tight enough. Wonder if anyone else has had this problem and would it make a difference if I replaced that part of the door. It is so annoying!
I have the same problem with my replacement slider. I am not sure if it is not a brand problem. Same supplier where I got my slider did not have supplier for the replacement for power cord hole cover. You might take yours to different outfitters as you travel and see if any are the extra 1/4" or so.
