Trouble with door, sagging wall

Today I was really taking a good look at the wall on the slide side and noticed a slight sag.  Can only really see it when really looking for it and a straight edge only moves about a cm when on the lowest point.  That being said, I can feel, and barely feel a slight bulge (vertical, feels like a stud) right over the top of the sag, which is directly under the farthest forward entry point of the slide.  I am trying to track down the outriggers, but have not heard back from FR and dealership was no help.  Assuming I can get the outriggers, I assume that this should keep it from getting worse, but not sure at what point it is too late to stop.

Additionally, I have had some issues with the door from the beginning.  It works fine sometimes and gets stuck on the strike plate at other times.  I always level within 1* using my phones bubble level and can’t seem to figure it out.  Sometimes it sticks and leaves the screen inside closed other times they both come out together (even though it was latched when closed).  Sorry for the rambling, just wanted to see if anyone has any ideas on where to go next.  My biggest concern is that there is an issue with the passenger side wall moving as well.  

One last thing, how off-center on the frame are your R-Pods?  I was sitting there looking for any issues in the wall and noticed that the driver side tire sticks out past the fender and the passenger side is tucked into the fender.  Took a tape to it and the distances from frame to the end of the floor are (6 1/2 - pass. 7 1/4 - driver).  Looks like it is only offset 3/8” but makes a noticeable difference on how much the tires stick out (or don’t) of the fenders.

Thanks for the reply.  I cannot speak for the prior owner, but I have always leveled side to side with the tires, then front to back with the tongue jack then bring down the stabilizers.  I have also noticed that it is typically worst when we have been traveling and while messing around with it today, noticed that it is almost nonexistent with the nose pointed up about 1*, but that could just be luck.  I will try lowering the tongue tomorrow and seeing if there is a change.
