I have a 1983 310 turbo diesel moho myself but am allways on the look out for a potential project for my friend. A 26' trailer would be ideal for his 5 person family with maybe the kids out in a tent.
I have allways suggested to him to get a complete trailer, as then you can decide what to keep, what to redo and how it all went together, BEFORE you take it apart.
I responded to this one asking about frame condition and if axles had been replaced ever to which he replied that he hadn't gotten to the frame yet and the axles are original. IF the interior is in good nick and all there, with most likely frame and subfloor issues (which doesn't scare me as I replaced most of the subfloor in my moho and renovated the interior), what value would you place on this trailer.
