2010 RED 38QBA, 9,700 miles on it, yup, 9,700!
Rear slide driver side would not go out without much manual labor persuasion. It would pull in OK, but have a sudden oomph sort of drop as it was fully retracted.
Before I go much further, let me say that I bought this coach a month ago...didn't run, didn't drive, no communication from dash to ECM.
Got it very cheap. It had a minor electrical fire, I had that repaired in a day or two.
It also has a butt sag, which is a known common problem, or so say the Tiffin service guys in Red Bay.
Anyway, back to the slide out. It seemed to be getting stuck under the front of the bed as I tried to extend the slide. The slide would start to extend, then jam on something under there, and just stop. With a bunch of muscle and some leverage, I could get the front part of the bed(front towards the windshield) to "pop" up over whatever it was, and then extend normally.
I was concerned that the butt sag was causing this problem. So I temporarily jacked up the rear of the coach with a couple hydraulic jacks and some square tubing.
Still no go, so it seemed like the sag was not the source of the slide out sticking.
After way too much time on the floor back there, I found that there are a pair of roller supports screwed to the floor under the bed frame.
Maybe some of you know this already, but I don't have any documentation or drawings of how this was built.
There's 4 roller supports, 2 on the floor under the bed frame, and 2 on brackets bolted to the coach wall. The 2 roller supports on the floor were not located symmetrically, the rear most one was position so that it always had some bed frame over one of the rollers. The forward most one was mounted too far towards the rear...so far back that when the slide out fully retracted, the bed frame fell off the roller!
It's kinda hard to describe, here's a pic. (forward is left, outside wall in down, rear is to the right)
To get at these supports, I had to disassemble some of the bed. There were no extra holes, so I assume this is how it was built from the factory. I'm sure that the dude that installed this support put it in that location because he (or she) couldn't access all the screws. The view in this pic is with the slide fully retracted, you can see that the rollers provide no support at all. I drilled a couple holes in the wood framing, to remove the hidden screw, and to move the entire roller support forward, left in this photo. In doing so, I made sure that one roller was always supporting the bed frame/slideout.
If you look carefully, you can see where the wood framing is chewed up from years of falling off the rollers and landing on the metal sections of the roller support bracket.
All of my typing probably took longer than me actually fixing the issue.
It all works as intended now, but I am once again impressed with the lack of engineering, design, and poor quality components and shoddy assembly in these coaches.
There are so many better ways to build these things.
Ultimately, I'll use this coach for a while and eventually sell it for a handy profit, but only because I have a unique skill set and attitude.
I truly feel for those folks that pay full price for something that looks great in the brochure, only to find that none of it is as it seems.
And the poor folks that have to pay shop rates for equally mediocre repairs...I'll just stop here.
So if any of you have a glitchy, sticky, clunky slideout, you may need to look a little deeper than just spraying some lube.
