Who has a camper with a slide on single wheel truck

Well I have my 855S Lance on a 2011 F350 6.7 Crew Cab SRW with no add on's except Timbrens..It carries it fine. Doesn't sway or whatever.
Much better then my 01 02 F350 with airbags,rancho's.. Ford did majoy upgrades in 08 that made the difference.
My tires are stock ContiTR's and they have been so good I am on my 3rd set. I've hit some bad potholes with the rig on and they've held.
