Where did you buy the delrin?

That's pretty much what I said about the timbrens except the timbrens include the spacer and no need to make your own. Of course, we're both talking about the rear and not the front. I don't think you can add a spacer to the front timbrens/sumos since they mount in that pocket like the sock bump stocks do.

I tested it with the 2400lbs of water. Without the spacer there isn't enough weight on the timbrens to stop the sway as the timbrens hardly compress. Add in the spacer and they compress a nice amount and actually do what I wanted. My rear is stock height.

adding after mod pic... sorry for multiple posts... forum rules do not allow me to edit posts anymore...

Good job. Does the axle rust take a toll on the Sumo's or do you remove them?

Okay, I have only followed this thread loosely, but when I've been hauling heavy campers on pretty darn miserable "roads" and trails, the less sway bars and other interference with suspension travel I had, the less the camper swayed.
Which, to me, makes perfect sense.

Absolutely. The next time I go for a run of more than 50 miles or so I'll disconnect my swaybar on one side. Articulation moderates the sway along with airing down. Back on the highway articulation is not your friend. You have a smooth surface(except in California thanks to the highest gas tax in the US)and want the body to be as parallel to the frame within reason. Too stiff and she's going over if you enter a turn too fast. A little body lean alerts you to slow down jerk.

Tap Plastics, there is a local shop near me.

I installed them and forgot about them. I checked them a couple of months back to make sure they are still tight and still no issues with them. I'm on dirt roads often enough to where it would be better without them but I prefer the flat truck in the corners. I have next to zero body roll on the streets.

How fast are you driving offroad? I take my camper over some pretty rough terrain, and although it can get a bit of a lean now and then, it’s very rarely too crazy. I usually run air bags with no other mods. Same tires as you with 65 rear, 55 front. Airbags at 90.

Not fast at all off road. It's definitely not a lack of articulation issue. It's treacherous with front sway disconnected. She gets rocking pretty good. To me, it's almost like it needs more shock rebound dampening so it slows the rocking.

Using Timbrens on the front axle off road to control sway will tweak the weak front axle tubes without a truss especially on the drivers side.

I wouldn’t be disconnecting my swaybar with the camper on. Shocks may be the cure you need. I’d call some of the suspension experts like Thuren or Carli. They don’t specifically build camper hauling shocks, but they sure know a thing or 6 about suspension.

I just put a set of Airlift bags in my truck tonight. Camper is going on tomorrow and then it’s off into the mountains with the fishing boat behind. I don’t expect any issues as I’ve bagged the past 5 trucks I had before this one and all were stellar on the fire roads.

Fire roads are fine. My issue starts when those roads turn to jeep roads. Even at a crawl, she feels like shes gonna tip sometimes. I think you are right on shocks as it needs something to slow the rocking down. Some sort of dampening effect.

I have a choice of other “weapons” for real off-roading. Maybe look at a pop-up camper to lower you cog if you want to take the truck on trails?

I have a set of the KORE springs that Danderson uses that I would sell you for cheap. And if I remember correctly, you're just up in Breckenridge. I'm in Colorado Springs.

So you did not read or believe the sticker in the glove box(owners manual pack) that said Camper payload limit was only 1500Lb and not recommended for 2500's for cab over campers. Dually reccommended. Simple as that. The Camper weight rating is only about 3/5 for the general cargo raging due to height and placement. Remember those reatings include 150# to 350# for driver and the same for any passengders., so you and your three hunting buddies, or wife and inlaws or three teenageers could be 1/2 TON+ parked in the driveway without camper., then 150# fuel, not counting extra fire wood or chainsaw, gun and tackle, clothes, tools, cases of water, 300# tongue weight for your fishing boat. AND THAT DO NOT EVEN COUNT THE FILLERS INSIDE THE CAMPER LILE CLOTHERS FOOD AND PROPANE.

THE CAMPER PAYLOAD IS NOT THE CARGO PAYLOAD.

So here are some thing you can do/add to help compensate.:

Start by reducing any cargo, passenger or accessory weight you can.
Find the thickest sidewall, highest load and heat rated tires available without raising height significantly. run good or upgraded sway bars front and rear and the added ones attached directly to the camper. Camper special overload springs in rear and HD Blistien or Rancho or better shocks. Stay out of high cross winds or head winds. Dump water and waste appropriately for trip home. Maintain max air pressure. If off road is not needed stick with highway it at tires like Good year or and Michilin

You need bigger shocks. Shocks will control the spring cycling. Probably need 2.5s with some heavier valving.

Do you have any suggestions on what brand and model? Everyone suggests the ranchos, but they seem to fail quickly. Thoughts on a dual shock setup?

Some good thoughts on here. My truck isn't quite the same as yours, but I have a 2001 2500 and I occasionally haul a pop-up cabover camper that weights around 1,600# wet and I have hauled cargo loads up to 4,000# (not for very long on that one, not recommended!!!). My suspension is all stock except I run the Bilstein 5160 shocks. However, my truck came with the "Camper Special Package" stock. My understanding is that the camper special includes 3500 leaf springs, rear sway bar, and trailer wiring. I have been happy with the 5160s for the price. They have a remote reservoir for more fluid to keep cool under high heat scenarions. Definitely not the same quality as a custom valved and tuned shock, but for $700-800 for a set I am happy. I don't get too much sway, probably because my COG isn't quite as high as a full hard side. My plans were to possibly install Timbrens or Sumo Springs on the rear as well as a heavier sway bar by Hellwig. I think a rear sway bar will help you out and I think the Bilstein 5160s would be a good addition. Good luck!

Some 2.5 kings from thuren probably. Big shocks with remote reservoir and heavy valving.

Just did my first shake down run after adding rear Timbrens. Couldn’t be happier. Body roll is sooo much better, truck is much more level and I don’t think they really effected the ride quality at all. I’d highly recommend them in your situation.
