My 2020 Adventurer 89RBS is about 350 lbs wet over my 2012 F350 SRW 11500 GVW Rating carry capacity. So...... I added Air Bags, Roadmaster Swaybar, 4500# rated Method Wheels 18” paired up with 4080 # 10 ply Rated tires. Two different Adventurer Dealers plus a Adventurer Factory Sales Rep told me with those upgrades that F350 SRW can handle that load. I’m comfortable with how the F350 handles the load especially with ditching that small OEM Swaybar. Some will say I need a DRW with the 4500 or higher Carry Capacity, I think not....
