If it is indeed 7 ft wide, then like I said, you should be able to get 2 full size quads in there easy with room left over. Enough should be left over that you can fit the minis in there.
Well, I'd agree it would be easy to get 2 in sideways, but that would fill the length up and leave about 18" or so in front of the 2. There's no way I'd be able to get the minis in.
But, I stood up the 'dale tonight, and I think I was at about 50". So, at Happy's suggestion, I pulled a bolt out of a front shock to collapse the front end. Strapping the front end down to collapse it would be too much, since it's got to go all the way down. That'll get me down to about 40". If the trailer is 7' (84") inside, I can stand up 2 x 2 and get 4 full size in their with 4" to spare on the width and a bit more on the length. I bet that'll be a tight squeeze getting them in place. I'm going to pull the Kawazuki up and see if it'll get about the same size. Lot's of if's in the situation. I'm headed to look at the Haulmark on Sunday, so guess I'll see then. Sure would be nice if it was a little over 7' on the inside! I'll have to come up with something slippery to slide the quads on- I don't think there's enough height to use some dollies. I figure a piece of carpet will probably work pretty well.
