Didn't know they did that.. if I can just remember until I buy my next rig in a few years... I am actually considering a crossroad as my full time rig..
I didn't get that automatically with my current TT, but I did negotiate with dealer for a roof check/clean/treat about 6 months after purchase.. and I did use it. He still made out, because by that time, I had other stuff I wanted to buy and have installed.
