It is the same rubberized suspension that is on the SUT-200-S. I learned today that this trailer is actually shorter than the S version. It is 12' 6" long from the tongue to the tail. I also have looked at the tracks and there are other mounting holes to move each track 1.5" towards the center (I noticed that my coworker's scupper tracks on his Pescador 12 are closer together). I figure, add some pool noodles and I you could probably accommodate any 10-14 ft kayak.
