My trailer is getting some age on it and has never had any roof maintenance done so I think it is time to get it done. I had a vent start leaking on our last camping trip so I figured why not just do ...
Here is a link to a similar project I did on one of my RVs (...actually, did it to 3 of my RVs). Very easy to do. I used Dicor roof sealant because I had a few gallons available, but I imagine other similar products would work the same. So far it's holding up perfectly. Never had a leak.
