the way mine is set up on a 7x16 trailer. i put up plywood walls 4' high 8'long to make a 8x7x4 leaf box with an open top. go to harbor freight and get a netted tarp(regular tarps will not release the air in the leaf vac and will create a big mess whereas the netted tarp lets the air out and keeps the leaves in except for the dust which is no big deal. then I mounted a 13hp homemade leafloader on the tongue and shot the leaves in through the front of the trailer. when unloading it is nice because there is a farm around here that has a large field to put yard waste and i simply take the tube out of the hole in the box and shoot it into the field by putting the vacuum tube in the box.
