Sumo Springs?

I have been wandering about through the various other Class B threads on the Sprinter forum. In the Winnebago threads, especially, it seems that a lot of folks are installing SumoSprings on their Sprinters. They are mentioned quite a lot.

Does anyone here have experiences good or bad with SumoSprings? They apparently replace the stops on the springs with softer and more progressive rubber stops that have trapped air bubbles that compress and cushion impacts. They come in several different densities; larger air bubbles being softer.

I have given some thought to adding them. I'm not especially close to GVWR on my Interstate, but Louisiana potholes are murder!

Never mind. Discovered that the sound bar won't mount to my cabinet all at all unless I remove the television mount, which kind of defeats the purpose. So I hooked up the sound bar to my home television, and I'll just use Bluetooth headphones to listen to the TV in my Interstate.

Grab handles installed

Here are shots of the grab handle kit and of the roadside handle installed.

The quality of the handle is great and the kit is well packaged with good instructions. Their method of expanding the RivNuts is a bit awkward using two wrenches on a bolt and an oversize nut. The RivNut wants to turn when you want it to stay still. After the first RivNut was set, I had the drill down and the remaining nuts went much faster.

You will need a pop-rivet tool.

The handles are not in the line-of-sight to the mirrors.

I had been grabbing the steering wheel to get in. The new handle is much better located and makes getting in a lot easier. Probably safer getting out, also, since I know someone who took a tumble getting out of an AI. My wife is going to love her handle since she is not very tall.

Yes - they are great and if you look closely at inside surfaces of the handles you will see the Mercedes part number as these are OEM parts. This option became available on Sprinters a few years ago. You can get the same parts from your local Mercedes dealer for less, but TerraWagen has very cleverly packaged this kit for our convenience.

grab handles

I have to put in a good word about Terrawagen. I've been following the comments about the grab handles and knew I had to have a pair. So, went online and ordered them; their online calculator added in postage amount. Two hours later I get an email from them stating that they were refunding 1/2 the shipping cost because the online calculator gave a higher figure than needed. I answered back telling them that such honesty is rare - especially in a situation in which I never would have known the difference. Got a personal reply thanking me and hoping I enjoy the product. Refreshing.

Found drawer bins that fit below the sofa in our GT. A little Velcro under the back holds them in place on the carpet.

Seconded. As previously stated, I ended up ordering two sets of handles, thinking that I was ordering two handles. A quick email to Terrawagen, and they sent me a return label less than half an hour later so I can return one set of handles at no charge. They'll refund the cost as soon as the excess grab handles are received at their end.

I also suggested they add text to the grab handle web page to let future customers know they come in pairs. We'll see if they make that suggested change.

I have two trunk organizers that fit in mine...side by side, and they have dividers.

It is my pantry area when traveling.

Regarding Pahaska's SumoSpring question: I have the front and back sumo springs in our 22' AI. I installed the front set relatively easily but the rear were an exercise in frustration. You have to remove the oringinal leaf spring rubber stops and flex the Sumos into the clips. The problem is the rubber is very stiff and is very difficult to get it seated in the limited space to maneuver. After numerous attempts, I finally took it to a shop that had a lift and could get better access. I installed them in hopes that they would fix my crosswind handling issue (they didn't) but the front ones did help a bit on the sway when turning into a driveway. I eventually solved the problem with the heavier swaybar, Koni shocks, and better tires. Not sure what handling/ride issue you are hoping to improve but I would probably not install them if I had it to do over.

The only things I did for improving handling were a front end alignment and replacing the stock shocks with Koni Reds front and rear.

Still some uncomfortable sway when crossing the ubiquitous "mountable" curbs at any driveway in the New Orleans metro area, but that's a momentary issue at the beginning or end of a trip when entering my apartment complex's parking lot, and not worth spending a lot of money to fix.

Sumo Springs don't really help anything except to add stiffness to the suspension when the springs try to bottom out. Unless you're in the habit of carrying heavy loads aft, or towing a trailer with a high tongue weight, the Sumo Springs on the rear won't really help. And Sumo Springs on the front really won't help under any normal circumstances, because you will almost never come anywhere close to bottoming out the front end.

In fact, in the New Orleans metro area with its rampant potholes and pavement uplifted by tree roots, Sump Springs would make the ride worse, not better, because the ride would be stiffer and more of the force of the up/down impact force from hitting potholes or bumps would be transmitted to the frame and thence to my derriere.

Good find !
Here is another good storage solution. Good quality with locking lids. Two of these from Container Store stack in the GT rear bin and I still have room to the side and 2-3 inches on top allows my tool kit to just barely fit under the lid.

Thumbs up Sumo Springs

Regarding the Sumo Springs, I must respectfully disagree with the above post.

We have a "SOB" (2009 View / 2008 "Dodge" Sprinter 3500) but the same Sprinter chassis.

We installed Sumos on the front and did notice an improvement.

What really surprised both my wife and I was that the ride was actually _softer_ over small imperfections. Both of us assumed that the ride would be stiffer.

Unlike the the stock bump stops, the Sumos are in constant contact, even with no load.

They are essentially a progressive rate air spring. In fact, one of the owners of SuperSprings (mfr of the Sumos) told me that we might as well keep our Firestone Ride-Rite airbags on the rear because they perform about the same as the Sumos -- and the Firestones are adjustable which we like because we usually (but not always) carry a Suzuki DRZ400 on a hitch carrier.

The Sumos help some with the push from trucks, but it is still there. With most trucks it seems to be less, but every once in awhile we still get a good shove. I haven't figured out why that is. Wind speed/direction? Size and shape of the truck?

In short, they do not work miracles but I feel they are worth the money.

Hope that helps.
