I don't have a TT Rover, but I do have a TT Cruiser (tadpole) and a Sun EZ3-USX (delta). I'm headed out to Ashley, Ohio (Buckeye Dulcimer Festival) by way of Wheeling, WV and Columbus, OH on March 9th and returning March 13th. If you'd care to test out either, I'm sure I could find room on the roof of the car for one.
