This is where I bought my newest TT, and had good experiences as well.
When I bought the TT, I also got my ProPride hitch. They let me install it myself right there in the lot. They poppoed out during the install (in the middle of summer) and brought me some water and evel allowed me to borrow a socket that I forgot.
Have a little warranty work (seal tape on one of the slides isn't looking right, but not leaking...yet) to do this winter and will surely take it there.
