Just purchased a snowpro/cargopro, (owned by Thule). It's 7/14, with a 4ft V nose, Tandem axle, 5000 pound capacity, etc. I've got 6'-10" interior width. I'm planning on hauling three bikes to Myrtle beach in may. I can haul two bikes staggered easily, but when I add a third chalk in the v nose, it looks like I'l be able to have three. I had them build the trailer with in floor tie down rails. The center rail goes all the way thru the v nose and the other two tie down rails are 4" from the walls. Easy folks to work with as they'll pretty much build it the way you want it. Nice black finish, with a diamond plate stone guard. Front right side of the v-nose folds down for snowmobiles. The rear ramp folds down and I got a side door put in.
I also added a wall mount bracket fo my removable seeg tour pak.
I'll post some pictures when I try the 3 bike set up.
