Ok so after dealing with FR on this issue, its left a sour taste in my mouth about how future issues will be handled.
That being said I installed the dexter #10 spacer kit Part k71-707-01 I ordered it from Find it Parts, who then ordered it from Dexter $64 out of my pocket( including 2 day shipping) and it was here in 3 days
Before under the dinette and trailer unloaded( no water no gear)
After the spacer install, again no water no gear
The Door side after( sorry no before)
and Finally the total package with TV
It was under 1 hour to install, the longest part was getting the trailer on jacks/ stands so the tires had 3 inches of clearance below them, as once you add the spacer kit you'll need it to get the tires back on.
I then had to flip my 2 inch drop receiver so now is a 1.5 raise to level everything back out.
Air tools and a good Torque wrench will be your friend on this install, as well as having 4 jack stands, and 2 jacks
