Dunham Travel Trailer Rebuild

I have purchased an old travel trailer for hunting. It isn't pretty but should get the job done. I am not sure if this is the best forum but am looking for a place that will help answer questions as I tear it apart and rebuild it. I am very handy and have restored Cabin Cruiser boats (head, galley, berths etc) but I have not dealt with propane equipment, the boats have only electric (AC/DC) equipment. They layout on this thing is not my ideal so I am looking at the feasibility of changing it. From what I can tell it does not have a water tank, nor does it have holding tanks although it has a head and separate shower. If this is the right place I'll have pictures and lots of questions...

thanks
