But I have a question. When doing the sides of the roof, do you completely cover the moulding and the rubber insert right to the drip rail? Or should I just cover the top of the moulding? I will be doing all vents etc., and front cap also. Basically if there is a slim, remote, miniscule chance water could get in.... It's getting eternabond

About five years ago, I covered the side seams of my fifth wheel with 4" wide Eternabond, all the way down to the top of the drip rail and right on top of the vinyl insert and cleaned caulking; there is about 1 inch of Eternabond stuck to the roofing material, then an inch or so stuck to the caulking, with the remainder attached to the railing. It is still stuck firmly today.You probably already know this, but:Clean the drip rail and roof area thoroughly; all chalkiness must be removed as well as all dirt. First I cleaned the area with a liquid cleaner and a brush and rinsed well and let it dry. I then used naptha, sparingly and carefully and it worked well. Others say to use acetone or Eternabond's branded cleaner.Eternabond is the stickiest stuff ever. Apply it carefully. I tried to align the bottom edge of the Eternabond where I wanted it to end up on the drip rail, and then folded the remainder - evenly, carefully, and a little at a time - over the edge of the roof.Roll all the Eternabond firmly down.

I covered everything and part of the drip rail. Clean well before applying and use a roller.

Yep, got a roller too. I wonder if they could use a single large sheet of eternabond instead of TPO, or epdm... Wonder how that would work for a roof membrane... I think it would be the closest to a waterproof rv there could be

It would be expensive but probably a lot less than a new roof.

I can just imagine dealing with a 4' wide roll of Eternabond...

Actually with two people it is probably quite doable, and the cost is probably less than a new roof install

I agree it'd be doable, but it wouldn't be easy.

You got me curious, and I found that a 48" x 50' roll of Eternabond is $960. 10' wide EPDM rubber membrane is $16.55 a foot.

I ordered mine off Amazon, at the time they had 3", 4" & 6".

You might get some ideas on using Eternabond for sealing your trailer by studying the link in my signature and pay attention to the captions on each pic. I cover about everything you can use Eternabond on including screws, both with exposed heads and those under the vinyl trim molding and clearance lights.
