what should be done to the suspension of your truck

Great Discussion Thread on Truck Suspension. I have been through three Truck Campers and three FORD Super Duty Trucks in 25 plus years of truck camping. I have been through Super Springs, Overload Springs, various Anti Sway bars, both brands of Air Bags and Shocks from stock to Rancho 9000XL. Never felt we needed a front anti shock or anti sway suspension shock.

I am the most pleased with our current setup on the 2012 F350 6.7L Diesel Super Cab which has Stock 18 inch load range E Michelin Tires, Timbren Suspension System, stock Ford Sway bar (Hellwig would undoubtedly be better), Rancho 9000XL Shocks and last and best addition the Torklift Quick Release Stable Loads. Just finished a 2000 plus mile trip through Nevada and northern California and eastern Oregon. Lots of varying road conditions and lots of wind from every direction. The Eagle Cap 950 appropriately loaded and the Harley Hauler Enclosed Trailer behind.... all traveled very nicely with very minimal sway and roll.

Again Great Thread

Funny you should mention the F550. I owned a 1994 F350 7.3 Dually and had a 1994 Caribou loaded on it. 3500 LB dry weight. As others have mentioned probably 5000 lbs loaded. Camper was well over truck capacity. Rather than start modifying the F350 I sold it for $4500.00
and bought a 1999 F550 for $7000.00. No weight issue, No sway. Rides much nicer. Going to the F550 was a great move for me. YMMV.

when I use the air bags, which were put on to haul my 5th wheel. I only fill them up until my rubber bumper barely engages the over load spring. the rear rubber bumper engages the spring about 1 inch before the front bumper does so I only have the rear bumper engaging the spring until I hit a bump and then I am sure the front one engages.

If your overload springs are not FULLY engaged, front and rear, you have too much air in the airbags. That is your problem.

Unless the springs are engaged front and rear, they're not doing anything. When you hit a bump, they're "slapping" and giving you a harsher ride than necessary too.

Let some air out. If you don't like how it sits, get some Torklift Stableloads to make the overload springs engage sooner.

WOW, now that is something special! Shocks, airbags, rubber stoppers, leaf springs all in one. This could be the answer to all the questions.

Thank you for the post

Here is the link to RAS: http://www.activesuspension.com/

The idea behind this upgrade is that a coil spring is stretched as the leafs are compressed helping to preserve the leaf spring arch.

I am sorry but I do not know what an Active suspension upgrade is or a RAS. Could you please explain? Thank you.

When I say front I do not mean front axle I mean front of the rear spring/

I hope there are people out camping. I got my slide out awning installed and I am ready to rock and roll all I need is the family not to be busy.

Thank you all for the information

Camper on ,put 5 lbs in the bags just so you dont damage them and drive it ,see what the differance is . I suspect it will take most of the roll out , then look at how unlevel your truck is if at all and deal with that by leaf spring mods , if you want to , if its not sacked out maybe dont bother
Once your comfortable with the truck , how much is the tongue weight of the boat trailer , thats what you deal with
Unless its a real small aluminum boat , have brakes on the trailer
Adjust your driving style to the load

I had an interesting conversation with Roadmaster earlier this week. They suggested I keep the OEM sway bar and use the active suspension upgrade for best anti-sway. Their thought was that there was more value to adding RAS than replacing your existing sway bar. If you do not have a sway bar, then you should add one.

First you need to see how the camper sits on the truck. If it is level front to back and left to right then no need to add to the suspension.

Normally the stock shocks on pickup trucks are not really up to the task of dampening a heavy load like a camper. Replacing them with Bilsteins or Rancho shocks is a good idea.

Some trucks benefit from a rear anti-sway bar and the Fords more than most.

In terms of load capacity the limitation is usually the tires and with DRW this is not going to be the case as there are twice as many tires to carry the load.
