I bought a new to me TT that is in really great shape and had very few areas of de-lamination. I noticed that the dealer the folks I bought it from who they got the unit from a year ago, went over it ...
I've noticed all the photos and videos I have seen of this seal test method have been on aluminum sided trailers but I have not seen one with Fiberglas smooth sided ones like I have, has anyone got experience with those type of TTs?
