From what I can tell you are not supposed to use the aluminum camper bed as tie down for a slide in camper. So decided to go with TorqueLift frame mounted tie downs in SRW 2017 Crew Cap with 6.2L gas with a 2004 NorthernLite 10.2 camper (~2350 # dry).
Just ran this rig over the Denali highway, which is the old road into Denali National Pak with no problems. The Denali Highway is 100 miles of gravel 30 miles of poor pavement. It is good test of your vehicles tires and suspension. It is also known to claim a transmission of two. It also has a 100 mile stretch without cell service.
Ride was better then my old 2005 F350 with 6.0L diesel which developed a dramatic high pressure oil leak. 500 PSI minimum is required to fire the injectors on that vehicle and when Ford tech service said you had to remove the cab, it wasn't worth cost to fix it, so asked the Ford dealership what to you have that replace it.
