A little late to post....
I bought a '13 dual ride up Kendon in Dec. Wanted a small trailer to keep in garage that wouldn't take up much space since I figure it'll be a 1-2 times a yr use. Was used to tow 1 time by original owner, then just sat inside.
Still has original bias ply tires (with nubs and all). I towed my SGS round trip from IN to FL over Xmas without incident. Towed behind my '16 Ford Escape and I couldn't tell it was behind me. Towed straight and perfect at speeds of 80mph w/o a worry. Only drawback I can find is lack of tie down points at back of main floor to strap back of bike down good. I was strapped down 2 at forks, 2 at engine guard, and 2 at mid frame right in front of side covers. Took some time to route straps and avoid any paint rubs. I'm going to install 3 tie down points at rear where tail folds up to help keep rear tire in place. Also gotta watch the license plate when loading on left side. It extends into bike path when loading. Putting a wing nut on the right screw so the plate will swing down and out of the way for loading/unloading. Considering the rock guard. In short, I really like it
