I doubt that you would have to have them, it depends on how much the truck bed drops when you hitch up the 5th wheel.

I'm a firm believer in the bag system. They really help reduce the chucking when hitting bridge joints. Part of the cause for chucking is when the suspension hits bottom on large holes or road seams. The bags help prevent this from happening.

GM's don't seem to need Bags as much as Fords. We hauled a 36RL with almost 4K of pin and now our 39MB without Bags. And we've put well over 50K miles between the two units including trips to Alaska and Newfoundland.

I noticed a huge difference in handling after I installed the bags

I have them on my 08. You have more rear spring than me, but maybe more pin weight. mine is 3300#. I have to go along with Dave about helping to not bottom out. You might only need 30 or so pounds.

I have them on mine with onboard compressor and would not be without them. I am running close to 4200 pin weight and run my bags at 40 psi helps the rebound coming off bridge joints

**Dave&Ginny** · 11-26-2016, 05:30 PM

I think for the costs.......worthy investment.

So guys looking on line for the best deal on the bags. Another point, with the TV centre in a slide then the kitchen with oven hob micro fridge and then upstairs bed slide with washer up there do you think air bags under the driver side of the trailer would help with weight on the springs.
Thanks Den.

I would hope they wouldn'tbe needed . You would have to build your own mounts. I've never noticed any leaning that didn't have some
other problem.

You can install the Centerpoint air ride from lippert on the trailer. It has a air chuck for each side. I run 60psi on the curb side and 75psi on the Roadside as it is 700lbs heavier

I believe the CenterPoint Suspension system that Lippert offers is to allow air adjustment to a heavier side. Each side is adjusted individually. I believe the new Redwood 2017's are coming standard with that system.

I forgot about that one.

If you are considering putting air bags on the 5th wheel you need to install a center point suspension from Lippert with seperate gages( 1 for each side). If you can and do the job contact Lippert "Magan" at the service center and have them do the work. They are great. Had a bunch of stuff done by them last summer. What this does is helps the motion of the unit. Then there is 8k axles. Then the air bags on your truck is to assist the truck springs and give you a more stable ride. "OH yes" also the Flex Air pin box i really nice too.

Have fun ....I did....

I put Firestone air bags on my 2012 F-350... the trailer weight wore out my front tires in a summer due to the change in tire angle (toe/camber)
My new 2016 Crew Cab F-350 seemed to ride better this year with no tire wear... the truck drops about 1-1/2" when the trailer is connected. I played with the air in my Trail-Air hitch as well to reduce chucking.

How did the weight of the fiver wear out the front tires. The weight of the trailer even with bags should take weight off the front

I ordered a set of Air Bags from Jet the best price I could find.

BradPAjax · 12-01-2016, 12:53 AM

Shane,
The LACK of air bags on my 2012 F-350 caused the wear because the front end was lifted. I added air bags to that truck to correct the problem and level out the truck.
The new 2016 crew cab seemed level this summer and my recent vehicle inspection showed even tire wear on all 6 tires so air bags are not necessary but may be added to help with overall ride and trailer chucking.
