I'm unclear why you would think that. Your wheels have you at 7.8K pounds, well above the stated 7K GVWR. Which tires, axles and spring packs are riding under your Hull #045? How much does your trailer weigh full of water, gear and ready to camp for a 3 month long foray?
The wheels and tires under my Hull #050 have a load rating of just over 13K pounds.
The Axles are rated at 10.4K pounds.
The Alcan springs can support 11K pounds.
The Outlaw Oliver has always weighed well over 7000 pounds in its natural habitat. And, it has traveled over 100K miles, most of it with the tires sitting at 80psi all without a single issue. I'll be forever grateful for Jim Oliver's guidance and assistance in designing the most over built Oliver rolling down the road.
But, there are those here that think I tend to over-engineer everything.
