I downloaded the qualifier for this system. Because I have the TT leveled with blocks in my driveway my wheels are not sitting flat. I call MORryde and they said it should fit but to be sure that I should hook up the trailer and tow to a flat surface. Looks like that most dimensions will work. They are really close. Has anybody installed one of these yet ? Trying not to disconnect everything and look for a parking lot that is relatively flat if posibile.
