Much to my dismay I recently lost the rear service panel on my 1968
Safari 22' and, as suggested in other forum threads, was the result of rear end separation which we are now in the process of getting fixed. Not cheap but it will be done right and coupled with a new axle she will be a much happier camper.
So we did order a replacement panel from Inland RV and I can say that overall I am satisfied with it but it is not a direct replacement for the original. I will forever be on the lookout for an original replacement.
During the same trip, the original window to the right of the entry door shattered. I also ordered replacement curved glass from Inland and am pleased with it. Read other forums threads and info on the web as the curvature is not exactly the same. Also the glass is a little thicker but with patience I was able to get the old glass out out of the original channels and the new glass in and I am very happy with the results. Do not put in plexiglass except as a temporary measure. It is the easy way out and diminishes the value of the trailer.
