Well...I believe the origin of this problem is the front shear pin broke. Then I was trying in/out maneuver and got it all out if time between front and rear gear packs.....then I had inadvertently dumped the airbags.
So today I pulled all the pins and got the gears better aligned, then it was still binding in the upper front corner took me a few beverages to realize I had dumped all the air....I aired up the system got to "trave" height and now the slide goes in and out and in and out like it's supposed to.
I would say, there is a need to keep it at or close to travel height on suspension when moving slides in and out...that was a journey!
