I am getting quotes on a roll off container (my first) to fit my swaploader. One supplier offers a light duty, 16' box w/10 guage floor and 12 guage sides. Cross members will be 3" channel on 20" centers. Side height will be 36". I am not sure it will be heavy duty enough...and so here is my question. Will be using it for mulch, topsoil (up to 7 yards) hauling and dumping lawn debris, limbs, shrub tear outs, etc. I will not be dumping chunks of concrete, or tree stumps into it. No C & D work except occassionally dumping shingles for my friend in the roofing business when he has tear offs. OK, I like the idea of a lighter box as far as economy and available (legal) GVW. Based on the uses I have described, will this box be durable enough or get destroyed quickly? Its about 8 percent less $ too.
