You really should try and get to another scale. Those weights seem off to me, either that or mine are just crazy. I’ve weighed my truck and camper twice (af811 and 2018 ram 3500 srw) and I’m at 9k loaded on the rear axle. I’m heavier than everyone else online seems to be and I’m not sure why, but you may be as well. I just upgraded to 19.5 wheels and tires to handle the load and they’re a huge improvement for stability even when just in the camper when the truck is parked.
Check your compression on your airbags when the camper is loaded. Mine was less than 3 inches between the top and bottom metal disks for the bags and so I’m having to move up to the 7500xl series to handle the load. I have stableloads also which help but didn’t solve any of my issues on their own. I can only have the lowers cause rams don’t have upper overloads so if you have those too maybe they’re helping, not sure.
AFs are heavy and I honestly don’t know how someone can carry one safely and be under fire ratings and whatnot without a dually or 19.5s. Not saying that it’s impossible or that people don’t have combinations that work, but it hasn’t been my experience and I have what is supposed to be one of if not their lightest units.
