Hi, I own a 1986
Sovereign 26' and the front transition from wall sheet to under sheath has been coming off for awhile, I fixed it with duck tape. The other day on the highway the "good" side of the front transition, just to the side of the hitch came off totally. Upon further inspection I have a hole in the underneath sheathing at the storage tanks. (along with two front pieces coming off) I am guessing I will need either a total re-do or most of it redone, including the plastic transition pieces. Is this prohibitive for a DYI? If so how much in round numbers ($$) am I looking at for a pro to do it?
