Drip Rails Leaks

[bwney]

On our 3400, the drip rail on each side of the roof is 3 pieces. I've tried caulking the gap (from the outside) between the sections, but it never lasts long.

I thought about caulk from the inside, but don't want to impede the flow.

Maybe Eternabond on the outside, may look a little tacky.

Any good ideas?

Yeah, that is a bit cheesy that they make them like that.

To me, it's kind of like a building contractor scabbing 2x4's together to make wall studs.

You would think that they would be all one piece, but hey, we're talking RV manufacturing here! I wouldn't be surprised to see a unit with the gutters made from only the 2 foot long leftovers, all strung together!!!!

I picked up some of that clear awning repair tape that would probably do the job on the inside, although I don't know if it would last any longer.
