Bunk End Seals: To Miter or Butt?

I am replacing the flat seal that sits on the inside of the bunk door with some pinch welt as per Rockwood's recommendation. Either way, I'll be caulking the seams, but should I miter the corners so they neatly meet, or should I butt them up against each other?

Does anyone have any pictures of what theirs look like?

Thanks!

Skylinedrifter,
I'm not sure I understand exactly (but that's not a first).

Does this picture help?

If you can keep it one piece.

Completely! The ends are butted up against each other instead of being cut to 45 degree angles.

Do you notice any water intrusion at that seam?

None at all. The seals on my bunks have been pretty good to me.

I would miter them and then use a white silicone to seal the cut. Why take a chance?

I thought the same as well, but then I wondered if the force of sealing the door and fastening it down will be enough to quickly split that seam.

So, the plan is to put the pinch welt on as per the picture, but then I am going to add an extra rubber gasket behind that so even if water gets past the first seal, hopefully the second seal will stop it and drain it down to the bottom, between the two seals.

Spray it with silicone or keep it covered with baby powder so it will slide real easy. That should keep it from sticking or binding when closing. Still would use the miter tho'.

Its slow and exacting but I'd miter the seal but leave the very outer edge of the seal uncut and bend it around the corner, thus having 1 continuse seal all the way around. That's what I did with my ROO seal.

I replaced the seals, butting them against each other, just in time for some moderate rain this weekend. I am happy to report that they seem to have held. I also made a further modification, putting some raised rubber feet on the doors so that my screw-down latches don't bite into and crush the outside of the seals.

Of course, there seems to be another problem which I've documented here just in case anyone has some input.

Thanks!!

skylinedrifter, another thing to watch with the door is that over time they start to bend in the middle, thus leaving a gap even with the new seals. That's what happend with ours and propted us to trade it. It might be wise to made some sort of support for the middle of the door near the seal edge when the bed in in use.

Thanks for the heads up.

I noticed that bow a few weeks ago. Thankfully, it is minor enough where the new seals effectively protect it. I am still going to look for a way to put a bigger gutter on for some better protection. My wife's ex husband is a metal fabricator. he and I are going to try and engineer a solution later this summer.
