Hey everyone,
I'm new to the truck camping world and have a few questions

I have an 2017 arctic fox slide in on a 2015 f350 SRW with airbags and rancho 9000xl shocks. I upgraded the the rims from 18's to 20's and put on bf goodrich ko2 265/70r20.When I bought this whole package it didn't rock back and forth at all, now it will rock side to side 2-3 times when until it smooths out . I have it loaded fine and the tiedowns are snug. Trying to figure out what's wrong. You would think the upgrades would've helped it. going around curves isn't a treat either. I have 55psi in the airbags and it leveled just fine and have a very slight bulge in the tire but nothing to write home about. I want to use this as a beach buggy in NJ but there's no way I can do that with this sway/ rocking. Any feedback would be helpful. This is dry weight... 4k Hate to see adding an extra 1k loaded would do.

Thanks.

Sounds like your airbags are overfull.

Based on what I found online, your rear tires are way over capacity. They are only rated at 3000 lbs each. Your rear tires are probably overloaded by 1500 lbs. I agree that your air bag pressure is really high. Buy some extended bump stops and make sure the overloads are engaged.

But, the main issue is probably the tires.

What tire pressures are you running, and what are your shock settings for front/rear?

Rancho 9000 shocks tend to wear out extremely quickly.

Read the thread below yours, literally the same question about virtually the same size/weight camper on a very similar truck.

Your post says you upgraded the tires and wheels and now it's rocking. My brain says you also upgraded the shocks and added the airbags also and prior to, you were riding hard on all spring and no bags and as soon as you lifted the truck off the springs at all with the bags, the body roll got more pronounced.
Your answers are in the "too much camper" thread.
