I'm getting a new dump truck this week and decided to go with a aluminum dump body.. primarily to eliminate the rust problems we have in the North East and also to save weight capacity. I'm going to have a salt sander I. The bed during the winter months and needs to strap it down. In the past, I have had d rings welded inside the steel dump body's and it was fine. Not sure if aluminum is strong enough to do such a thing. I'm guessing the pulling pressure on each ring with ratchet straps may be 1000 pounds +\-.. but again that's just a guess. Anyone done this before with aluminum ?
