Greetings -

My door has been out of alignment for quite a long time and I finally got around to some investigation. Early 1973 23 footer.

The PO had installed non-factory weatherstripping around the door. I replaced that years ago with the proper part and that's likely when this situation developed.

I've always suspected that the weatherstripping was preventing full door closure - but figured door misalignment or curvature was an issue too.

So. I removed the weatherstripping and thoroughly cleaned (wire wheel on a grinder) off all of the adhesive. I did this to have a better view of clearance or interference. I was pleasantly surprised to discover that the door works pretty well. Two closure clicks. Could be a little better - but pretty darn good.

Upon further investigation - I see that the upper right corner of the door (from an outside view) closes closer to the coach than the bottom corner does. So much closer that if weatherstripping is in that location - the door won't close completely. So... I'm considering "curving" that quadrant of the door outwards.

Any thoughts or ideas about how to do that ?? Anyone done it before ?? Or any other known remedy ??

Thanks in advance,

Pair of 2ft long 2x4s, adjustable c-clamps and rags to pad their points...Remove the window if you can first...One 2x4 flat on the door in a diagonal from upper left to mid-door right, clamped in place, you would have to space it off the window if you can't remove it. The other 2x4 perpendicular to and on top of the first, the end at mid-door left being clamped to the door and the other end sticking out away from the upper right corner you wish to pull back out. Use your 4th C-clamp to squeeze the right upper door corner and the protruding end of the 2x4 together VERY CAREFULLY, a little at a time.
I'm sure you will break the window if you don't remove it when bending that part of the door, no matter what method you use. That's what would happen to me Rolling Eyes

I have never had to do this. But it seems to me if the door appears to be curved correctly for the curve of your coach and the hinge side of the door is slightly too close to the body that moving the pivot point away from the body that distance might work. At least it might be easier than taking the window out and putting it back in later.
You can always bend the door if adjusting the hinges does not work.

Thank you Terry !

Your proposed method makes perfect sense.

Do you think it could work without removing the door from the coach ?? Sure would like to be able to monitor progress with door closings...

Perhaps I'll clamp the upper left to mid right 2x4 to the lowest right side location where a C clamp will still bite - and clamp the upper left such that the second 2x4 will still get perpendicular placement. Here's a case where a picture would clarify things - but I'm at home in pajamas, the coach is at storage, and it's raining. šŸ¤”

Thanks again,
Steve W

Steve,

If, as seems likely, you find your door needs a more general re-curve,
here's Dan Winchester's great technique. I've used it successfully several
times.

Wow...what a great idea! It seems like by using longer "L" shaped rods that you could do the reverse on the other side of the door to open the curve? JWIT

Yep. Just be sure to use a well padded force-spreading device on the
finished surface of the door.

Wow! When I tackle the door on AaRVee I know what method Iā€™m going to
use. Full control for perfect results!

Hugs,

Definitely intended what I said to be done without removing the door. Checking the results would be major PITA if the door is not hung in the normal position. The 2x4 that controls the bend point does not have to be the full 2 feet long, just enough to span the distance between the two bearing points. If you only want to bend the upper corner, find where the deviation in alignment starts on each vector (side and top0 and adjust your length to fit so you can still open and close the door during the operation. If you cant find any deviation in the top rail, maybe just run the cross piece all the way to the top other corner.
