I'm finishing up my leaf box and I'm wondering what I should use for the top. Like most issues, a search of the archives didn't provide a cut & dry answer, so..... Should I use a breathable tarp or plywood? If a tarp, should it be canvas, or mesh pvc? PVC doesn't seem as though it would hold up. If it matters, leaf box is on the back of an F350 dump. Leaf loader is 16hp little wonder. Also, I have an 18' foot trailer. I had thought I was going to put the leaf loader on the tongue, but if I have the room, wouldn't it be just as easy to install on the trailer deck, then take off after leaf season? I'll still have plenty of room for equipment. opinions please, thanks.
