I am confused. Firstly because I am not familiar with the roofing membranes in use TPO EPDM etc ... always had metal or fiberglass.. anyway I now have a GD 297 (2019) and even my liturature that came with the coach did not identify, it actually mentioned both EPDM and TPO. Dealer was not much help, got both answers there also. The GD website where I looked it up said TPO.. so I am going with that as I can't tell the differance.

I want to remove the vent in the front and replace it with a fantastic fan. Something so I can draw air in and have the other fan take it out in the back of the trailer. What sealer should I use? For most of my investigation it seems that something called 1021 is what I need, but I have also seen other stuff recommended.

And does anyone have an easy way of removing the old sealant? In my experience it can be a real pain in the patootie.
