Let me add my limited knowledge to this mess.

One, for some unknown reason, over time the top of the HWH slides tend to tilt inward at the top. Inward so far that that lip of the slide out would interfere with the bladder seal. I am not accusing anyone of anything, but sometimes some people who should have known better, simply BENT the pin mounting mechanism to get the pins to go back in the hole without ventilating the slide roof. When I look at your picture in the first post, one could guess the pin mount was bent and rewelded. There is definitely signs of a reweld on that mount.

I have studied the HWH mounting/ slide mechanism for HOURS and never figured out why so many of the slides tilted in at the top.

The solution is to mount an aluminum plate to the exterior of the slide to stop the top of the slide flush with the coach skin. If you don’t have a slide topper, it can be mounted in the corner. Jack’s coach has such a device, perhaps he will be kind enough to post. If you have slide toppers like I did, mounting a plate in the upper corner will cut the awning. So I mounted the plate low enough to clear the awning. I used rivnuts set into the interior bracing of the slide structure. Before you guffaw at this solution, it works like a dream.

Once you get the top of the slide aligned, cut out that mess of a mount for the slide pin lock, and weld it back in place in the proper position.

Not intending to be critical, just understanding of different perspectives. Sometimes a shop’s perspective can be to get you back on the road as quickly as possible. That may not be the long term fix that a caring owner would prefer.
