I am sure I am not the first person to run into slide out issues and there are lack of information on the web if you are a "do it yourself" person. I thought I will post my experience and share what I know.
We have a 2006 Coachmen Freelander and our slide out is not centered (tilted to the right side) so there is a gap when it is in the closed position (we can see major sun light inside the coach). Our slide our mechanism is a Liftco Glide out, please note this may only work if you have a Liftco also.
This is what it looks like before adjustment.
There are 2 large 1 1/8" bolt on each lower corners of the slide out. Adjustment are done by turning these bolts - Loosen it (counter clock when you are looking at it) will raise up the slide out and pull in the upper corner on that side. of course tighten it will have the opposite effect.
This is what it looks like after adjustment.
we still have to replace the seals all the way around the slide out as you can see in the pictures and the slide out unit is still not centered (tilt to left side) but since now the unit is sealed and tracks are not binding, I think we will leave it as is.
