It works great and doesn't seem to affect the Rialta negatively. I haven't weighed it in over a year, but I'd guess it's at ~7500 now with water and excluding 550lb bike, which has it's weight split with the carrier's wheel & RV when loaded. I have a leaky suspension airbag, but even flat, the rear doesn't bottom out or drag in dips. I've looked at the Pit Bull trailer restraint and the Tyre Down as options of better securing it without pulling down on suspension. Since that video, I've added self-retracting ratchet straps permanently attached to the carrier that grab a strap set up like the Tyre Down atop of my rear tire (see pictures in album) and plan to build a collapsible front chock soon. I had to take off the front fender of my bike to restrain it like I have been, but think I can make attachment for hooking on the outsides of the installed fender. Also added on the Rialta is a company logo on the doors and fleet numbers on the corners to appear more "utility van".
I'd be happy to help anyone out with dimensions or more details on the design; I built it in my Dad's shop at home, so can't easily reproduce one right now. If it's feasible to build the carrier frame with aluminum, that would help with weight, but you'll probably have to reinforce it in more places.Tynan, sorry for this post's delay; I didn't realize that uploading a video on mobile broadband was completely hopeless.
