Alrighty. New to the site and 2 weeks into the truck camper scene. Had a great experience with the dealer who was honest and guided me into the right directions for things and add on to the truck and did not try to sell me more than I might need. I have a 2017 Ram 3500 4x4 Crew Cab long bed single rear wheel with an Artic Fox 990 camper and firestone airbags added. I'm using Torklift Fastguns tie downs. I'm getting a lot of rocking of the camper in a front to back direction when going over bumps down the road and if the road is really bumpy the over cab portion of the camper almost seems to hit the top of the cab. The fast guns were set and labeled by the dealer and I feel they know what they're doing. Still...... I feel like I'm on the end of a bungee cord when driving getting jerked front to back. When going off road, beach driving mostly, I'm worried something may get damaged. Can somebody give me some advice on stopping this excessive rocking chair style of motion of the camper?
Thanks
Bill

I run the 990 on an F350 SRW and had the same issue. The fix? For the most part it was Rancho 9000's. The shocks are adjustable and I set the rears to 9 (hardest) and fronts to 7 and the porpoising stops for the most part.

Also added upper and lower stable loads which all but made the air bags an after thought now and added a Hellwig BigWig rear sway bar.

Lastly, don't forget tires! The 990 is a heavy beast at nearly 5000lbs when fully loaded so you will need good tires. I run the Toyo's which are rated at 4080lbs per tire
