It honestly will depend on the DOT guy that pulls you over.
A buddy has a dodge 2500 chassis cab rigged out for way more weight than the truck was designed for. Dana 80, air bags, overload springs, chip for appropriate power out of the Cummins.
most of the times he has been caught by the DOT, he has been empty. They usually assume he is a farmer, look over his truck for a road side inspection and let him go on his way. a few times they want to discuss what he has been hauling and why the truck is setup the way it is.
Caught loaded, without commercial or farm tags, your probably gonna be grilled on why you think you need so much wood if your not commercial or farm. You will prolly be fine for a while, the second or third time, you will have some esplaining to do to a judge.
