I have a 2008 3585SA that is located in a seasonal campground. (I know, sitting on blocks wasn't in their design)
The slides have never been perfectly aligned, but have been good enough to seal and not leak. When closed/retracted, they are up close and sealed well.
I went to open up for the season and noticed that all 3 slides are not lined up well enough to seal extended. They have two racks, gears and rod to sync them with a hydraulic ram on one side only. It doesn't make a difference what side the ram is on for alignment. I think the bed is the same, but it's under the plywood, so assuming. I triple checked the level to make sure it didn't get racked out of alignment over the winter and it is good.
The bedroom slide is even top and bottom on one side, but bigger gap on the bottom on the other side.
The recliner slide is good on one side top and bottom, but the same bigger gap at the bottom, tapering closer towards the top on the other side. The hydraulic ram is on the side with larger gap.
The dinette/couch slide is very close top and bottom on one side, but an even, but large gap on the other side. The hydraulic ram is on the side that's very close.
I don't remember having a manual on the slides adjustment. I checked some of the links here, but couldn't get the info for adjustment.
Is this something I can do or should I just call the dealer? When I questioned alignment before to them "it wasn't to be a concern". They might be happy to adjust when I"m paying
If anyone has more info or better links, please help me!
Thanx - Dean
