It may come as a shock to some, but RV technicians work on all kinds of "homes on wheels" from pop ups to Diesel Pushers. In fact, many don't even own one.
Yet somehow your units eventually get fixed by these "not my kind of camper" folks. A few have even come here for advice on a particularly thorny problem.
I would not turn away from advice received on an open forum from anyone, especially if the only reason was "they did not have what I camp in".
Remember, in the end, it will still be Caveat Lector (Reader Beware) regardless. Just because someone has your model of camper, he may know even less than you do.
EB works on ALL kinds of roof materials from rubber to plastic to EPDM to fiberglass. It also sticks quite well to aluminum fastening and structural materials.
