This is the one we have. http://www.discountramps.com/smc-600-motorcycle-hauler/p/SMC-600R/ We just got back from a 5300 mile round trip vacation with my wifes Suzuki Boulevard S40 on it the entire way. We went from the east coast to the grand canyon, and back and It was stable and never gave me any concern at all. My motorhome is 31 feet long with a Class 3 hitch the carrier weighs 88lbs and my wifes motorcycle weighs 380. The front of my motohome NEVER felt too light, and it did NOT affect the steering of my motorhome. I checked the carrier, tie downs, and the anti-sway device that comes with the carrier every day before we hit the road after the nights rest, and it was fine each time i checked. This carrier performed extremely well on all the nastiest roads i have ever encountered..... Im glad we bought it and it will be standard equipment on every trip we take now. ( i cant get the hyperlink function to work, so just google SMC-600R. And you should find it)
