Can anyone tell me if there are serial numbers "stamped" on a 5th wheel and if so, where? Friends of ours purchased a lake lot that had an old 5th wheel camper on it (abandoned - probably early to mid-70s model). The manufacturer tag (?) to the left of the door is so worn, if there is a serial number on it, you can't make it out. They are having trouble getting a title to it because they don't have the serial number. The model is the President by American Traveler. I think that company has gone out of business. We were told that it may be stamped on the axle but we looked there and couldn't find it. Any suggestions greatly appreciated.
