I've got the SU350 Trailex and it's 18 foot long. The kayaks carry inside the length of the trailer and I could easily cut off a foot or so from the rear of the trailer and not miss a lick. Moving the arms forward would make it a little heavier to move around as the center of gravity would move forward but it's not that big of a deal. Either trailer they sell can be made to fit inside your garage. I carry an Outback and the PA on mine. Love the convenience and when coming off the water cooked and whipped, it's not a big deal to load it all up, tie it down and go home. When I was loading it all on top, I was getting afraid to come back to the beach...
