OK. Here is my question.Suppose that I have purchased a dump trailer that can haul 5K.OK so I head to the quarry and get 4K pounds of stone.Now riding home the DMV sees my rig and pulls me over. secretly I am fixing a driveway, not for me but someone else. The trailer is all in compliance and insured. BTW, Trailer gross is 8K. Do I need a special permit to repair a driveway for someone else? Would this be a commercial use for the trailer? I plan to haul my John Deere 17G with it to the site. This is just a "Supposed Situation" .Thanks. Any constructive criticism is welcome, before I take the plunge, Ken
