Using
this link and down away are threads about FWS's and the changes made after 2016-2017. You have a 2011 coach which is a Newmar design.
There are many threads on the different slides and problems they may have and you will also find the slide spec's in QT's 1 & 2.
Prior to those years Newmar made their slide systems and they could be adjusted by you or Newmar dealers.
Some owners have done the adjustments with not to much difficulty.
