I have a 2015 RSSA and had mor ryde put on the 2 inch spacers. They measured my unit at 13ft. 5in. with the spacers. It is interesting when I go on the roof and see the scratch marks on the tops of the AC. Low hanging branches.
I do not think this includes the A/C units in the height spec or the 2 inch risers. With pick up heights these days, they should make the 2 inch risers standard. Better to have more bed rail clearance. Plus you can adjust the pin box or the hitch to make the coach tow level. I have 13'9" programmed in my GPS. As I wanted to have a couple of inches of play.

I will measure mine when I get on hard flat surface. On our bugout farm north of Tampa right now. Hitting open road tomorrow at 6 get around Atlanta traffic at 1am. The Chesapeake bay bridge tunnel is 13-6 so will have to drive around this summer from my flounder spot at wachapreague. Thanks for your help.
