Took my truck across the yard material place's scales and it registered 5270lbs. Fullyloaded with liquids, the truck camper is 3545lbs. Sooo..... , leave off a majority of the liquids I can until arrival at location sounds like a good start.
I think it's still time to make the trip down to the Pilot Truck stop and see what their scales read, but there has to be some merit in the yard mulch scales since it's their money making tool.
Thanks for the feedback. Bad news is still news. Better to know where you are than to be surprised. They delivered the camper from 120 miles away on a Gas 250 Lariat Long Box. He says he deliveres all over Oregon this way for the last 8 years w/o a problem, so that eases my mind a bit, but I'm still going to verify the weights.
