I did look at videos and made an adjustment that helped in one uneven part but the horizontal is the one I cannot do.
I talked to the Lippert rep who said what I described is very unusual and may require a lot of muscle to move.
For now we have the slide in and have elected to not use it.
I am (hopefully) attaching two pics that show the gap difference between the front (3 inches) and the back (3/4 inch).
The back is now so close I am afraid the window will catch on the wall when moving in or out.
In Dawson City now and may get to a shop when we can.
Thanks for input guys!
