Advice to reduce truck camper sway (2018 Ram 2500)

Hi all,

I have experience with fifth wheels and bumper-pull travel trailers, but am new to truck campers. Recently bought a very old Lance truck camper and I'm experiencing some extremely bad back-and-forth sway even when driving straight. It usually starts at about 45 mph, but gets significantly worse at ~60 mph. I've been told to expect some sway, but this does not feel safe at all.

My truck is a 2018 Ram 2500 (Cummins engine). It came with a factory rear sway bar, but I'm told that these aren't very good. It also has rear coil springs. I haven't had a chance to weigh the camper yet, but I believe I'm well within payload capacity.

I went with frame mounted torklift tie-downs and the torklift fast gun turnbuckles, so I think I'm good there. The truck bed has a very thin rubber mat (to avoid sliding) followed by half-inch plywood that completely covers the area of the bed where the camper sits (two 4' x 4' pieces of plywood). Also, the truck and camper seem to be swaying together, so I don't think the camper is moving, shifting, or sliding inside of the bed.

Do you think upgrading the sway bar to something better (Hellwig?) is the next best move? That's my current thought, but based on other research I've also seen advice to upgrade shocks/dampeners or maybe even consider an airbag suspension upgrade. I'd definitely like to try one thing at a time, but am looking for the biggest bang for my buck to reduce this ridiculous camper sway. Any suggestions?
  • Thanks for the replies so far!

    We suspect the slide-in camper is a 1994 Lance 480, but haven't yet been able to find the serial number of model number anywhere on the unit itself. My best guess based on old spec sheet brochures would put it at ~2500 lbs, but yes, definitely time to hit the scales!

    I don't have access to the truck or camper right now, but will check on the axle rating and exact payload when I do.

    Based on comments so far, I'm thinking I'll try a much better / thicker sway bar first and see how far that gets us since that seems minimally invasive. And then we'll consider something more robust. Timbrens look very promising if the sway bar isn't effective enough on its own...
  • I would put a set of Timbrens under your truck, go with the double convolute and adjust the ride height by removing the spacer if necessary.
  • I bought a 2018 Ram 3500 last year and put my 2012 Adventurer 86FB on the back. It swayed more than my 2006 Ford F-250 ..... but then again I added 5000 lb overload springs on the back which worked pretty good. For my Ram, I installed the Hellwig 7298 Big Wig rear sway bar and it helped tremendously. The sway bar is massive and is 1.31 inches in diameter and made of 4140 chromoly spring steel. Don't think you'll find a better sway bar. I've got some Firestone air bags that I'm going to instal, but there's a broken bolt that appears to have been over torqued at the factory and broke off. I can't get the dang thing out. Anyway, my camper is 2300 lbs dry and I'm guessing yours is heavier. Campers are generally at the edge of the limits for trucks, so I went from the 3/4 ton to the one ton ..... but my 3/4 ton Ford did great with my modifications.

    Just what year and model of Lance Camper do you have?
    It would also help if you post the trucks axle rating and Payload, one from the White VIN sticker, and the other from the yellow Tire and payload sticker.
  • I upgraded my F350 sway bar and the improvement was significant! Since I had a factory sway bar, I went with a RoadMaster upgrade which let me reuse my existing sway bar drop-downs. Previously installed StableLoads took some side-to-side sway out, but mostly they just helped bring the rear up to level.
  • I think your issue is the rear coil spring. Most of us would avoid them and pick a truck with standard leaf springs.
