Not exactly related, but I'd love to know what yours weighs when you get it and get a chance to have it weighed. We just got an 811 for my 2018 Ram SRW 3500 and I'm right at 9k on the rear axle just with that. The suspension (Airbags and lower stableloads) handles it fine, but I'm moving up to 19.5s to handle the weight from a tire perspective. I know these things are heavy, but the truck scaled at about 3500 on the rear axle unloaded, so not sure quite how I'm where I'm at and would love to see your weigh slip too. Maybe the 2021's have lead in the floors, idk lol.
