Does anyone use sumo springs or other type of solid rubber type of helpers?? If so, how do you like them, and are they working? Are there down sides? Would you install them again? I like the idea of install and forget. But if they don’t work I’ll go with air bags instead.

I'll chime in.
I looked at the same but ended up with air bags. Glad I went with the bags give plenty of adjustability between different trailers.
Pulling a 18' low hauler cycle trailer loaded around 7500lb's with 4 men in the cab and bed loaded full under a cover added 30psi to the bags.
With a two place enclosed snowmobile trailer 10psi. Truck just floats down the road with ether now.
I did pull the cycle trailer before adding the bags and new the suspension needed a little help.

I have the Sumo Supersprings on my truck, made a world of difference with the squat and bounce while towing/loaded. Adds the better load handling capabilities of air bags without the maintenance. The nice thing about the Sumos is they are progressive in the amount of support they give; meaning the more load they are carrying the firmer they are, and you don't feel them unloaded at all. Very unlike the Timbrens I had on a previous truck, which felt like every time they made contact for the slightest bump when empty felt like you hit a huge speed bump going down the road. Would definitely go with the Sumo Supersprings again.

Thanks for the input. From what I could research, air bags would give the best ride quality once you have the pressures dialed in, but then you have to change the pressure when towing/ not towing/ changing trailers. If the sumos don’t change the unloaded ride quality then that’s the way I’m leaning, just because of install and forget it quality. I worry enough about tire problems going down the road and don’t think I would be able to relax worrying about air bags too.

I have them on my 2020 supercrew PS and they are worth the money. I have a 8700lb travel trailer with 995 tongue weight and help big time with squat and trailer bounce. Maybe an inch of squat in the back when connected, with a WDH obviously.

I’m towing a 8000lb 5th wheel. Towed it from central Pa out to Yellowstone and a lot of other places out west on a month long trip last year. I put almost 6000 miles on the camper, and close to 7000 on the truck. The truck did very well as far as I’m concerned. The two problems were squat and body roll In windy conditions. Neither was severe enough to make me feel unsafe but I would still like to reduce both. If you check my avatar you can see my rig. As I might be going full time camping in the near future, I’m looking for a permanent solution with little or no maintenance. The camper is comfortable without all the electronic gadgets that will ultimately fail and be costly to repair or replace. Ah well, I’m getting off topic.
It sounds to me like the sumo springs do what they claim without maintenance and don’t affect unloaded ride, like helper springs do. For now I can install and they will work when camper is hooked up and do nothing when not.
thanks everyone
Mike

I run air bags on my 2019 not the Pancake style but the softer ones made by airlift. The pancake style require more psi when unloaded which makes for hard ride. I have them for 1400lb slide in camper which works very well. Truck rides like stock with only 3-5psi in them then air them up to 30 with the camper. Helps with the sway and keeps the rear from bottoming out. Only inconvenience is the fact that you have to air them up and possibility of leaks. I have had them for 20k and no issues plus they see many miles of dirt roads with camper allows lots of flex. I looked at the rubber springs but felt they would make the unloaded ride harder.

Still evaluting options. Anyone have experience with the Roadmaster Active Suspension?

Roadmaster active suspension "prevents" axle wrap by pre-wrapping the axle. It does this by putting tension on the rear half of the leaf spring which results in arching it more than Ford intended, and causes more load to be placed on the rear spring frame mounts. There are people who rave about the RAS, but personally I'm not a fan of how it does what it does.
