Sorry, you've come to the wrong place. Nobody on here knows anything! Just kidding!
You'll find alot of people on here that can help you with about any problem that comes up. Let us know if there is anything specific your wanting to know about.
Congrats on the new tt. Your gonna love it!
Just got my 8315ss 3 weeks ago. Camped last weekend and the only issue was a leak in the black tank flush. Just inside the tt where the water hose hooks up. Should be an easy fix. Other than that everything worked great.
Most people on here have had their Rockwoods longer than I have and can give you better info on how they hold up over time and any common issues that may occur.
