Lonetow, My GVWR is 9000 on sticker but I installed an add a leaf to each rear pack. Think it added at least another 600 pounds of support. I am going to upgrade to 19.5 vision wheels and tires to increase my wheel rating even though trucks forged Aluminum 17 x 8.0 rims have been great. Just had these inspected yesterday and being 8 years old they found no cracks or damage. Nitto Durra 285/75r/ 17s with 3970 lbs. load index have performed very well but cannot document forged aluminum wheel load capacity. Do not know if there Alcoa wheels. So going to 19.5s for added insurance due to size and weight of my Lance 990 legend 11' 3" dry bath model.
