I towed my RSR from Hartford to Watkins Glen last year using a rented U-Haul trailer
My RSR has been lowered and has the standard RSR type cooler valence. I had to make ramps out of 2X10's to get the car on and off the trailer. I also had to make small platforms from 2X10's to raise the car on the trailer to allow me to open the door and clear the trailer fenders.
