There is a GMC Pickup being ready for retail sale very soon capable of loading to 31600 pounds gross with or without trailer.
If it is all your private stuff you own outright,it's not a commercial vehicle. Sort of like a tool truck hauling all the bric abrack to the jobsite. You can and did put people into it with a basic car license. Even though you paid them by the hour they had a sufficient license to tool around in that tool truck following the rest of us to the new driveway job waiting to be finished. That is how we did sometimes with our tool truck which had everything down to the last bolt.
We both agree this crux you present is the bedrock of all this.
I appreciated your patience and know for sure the Motor Vehicle Commerical division as stated by Accidential Trucker will be sure to help you well.
