"Mark, Just writing to thank you for all of your help and guidance on how to handle the suspension 'rocking' issue on my new Navion RV. I purchased the suspension Package A for 3500 series. Let me tell you, it's a night and day difference that I would recommend to anyone who owns one of these vehicles. You'll wonder how you drove without it. I went from feeling like I'm driving an old stage coach to a sports car and the ride is no harder than factory. Thanks again, Rob"
"The Koni struts and shocks I purchased from you did wonders for the crosswind handling" - 2015 Interstate 3500 - Dave in Indiana. (Vehicle also has SumosSprings in all 4 corners.)
"I drove it the other day in a 20 mph cross wind with barely a swerve. I mean, it is still an RV, but the wind and truck swerves were barely noticeable and highly manageable, plus the ride is a lot smoother. I can not believe how much the sway bar made a difference in cornering. Thanks for telling me about the improvements. -Phillip" 2015 3500 Winnebago View (Customer installed front and rear SumoSprings along with 1.5" sway bar upgrade)

"WHAT A TRANSFORMATION!!! The new sway bar and rear shocks make it feel like a completely different vehicle. Where I used to "gingerly" take curves and creep out of driveways now I can drive with confidence. I think I should have opted for the front shocks too since the rear now finally feels stable but the front while fine does not feel as tight as the rear suspension. However I think I will get the Sumo Springs mounted first before adding Konis on the front.
I want to tell you that you have a great product package and service. Thanks much for your assistance. The little RV feels like a completely different van now."
"I am a "true car guy".....I have 8 Italian sports cars. I understand suspension dynamics and how it affects handling. Your package made a significant improvement to the Sprinter handling giving me more confidence when driving the curvy mountain roads in NC. My passengers also benefited from the better ride in the rear when we tailgated to the NCAA National Championship game in Tampa a couple of weeks ago. I should have found you years ago when I bought the van!! " Steve - 2011 3500 Pleasure Way Package B
"Mark, Picked the Ascent up yesterday with the new and improved suspension system. Made the drive from Va Beach to the OBX in fairly gusty cross winds and noticed a wonderful change. The coach no longer wanders/floats down the road and even the strongest gusts did not make driving uncomfortable. Handling through exit/on ramps was also much better. Thanks again for your assistance in getting the proper parts to me." Rob - 2017 Ascent - Sprinter 2500 Package A with front Sumos and rear steel SuperSprings
"Had the kit installed and just drove the Itasca Reyo. Completely different ride. No more sway. Drives like a car." John in NY - 2011 Reyo Class A on Sprinter 3500 chassis - Suspension Upgrade Package A
"Just a note to report upgrades installed and we took our first trip. Over Snoqualmie Pass onto Whidbey Isl. Huge improvement and very satisfied. Thanks for your recommendation. I'll refer your direction at every opportunity.
We picked up our MH new in Iowa and got blown and rocked around on the 4000 mile meandering trip home. Now all that is just a memory." Tom in WA - 2017 Navion on a 3500 Cab Chassis - Front and rear Sumos with upgraded sway bar - Already had HD shocks on rear

".... I WAS DRIVING AROUND IN THE MOST AMAZING RV ON THE ROAD!!!!! Seriously, the suspension package has made a night and day difference in the handling of my View. Everyone should be doing this upgrade! Thanks for all your great help!"
"If anyone is on the fence about the upgrade I'm also more than happy to talk to them.
Everyone with a Sprinter based RV should install this upgrade! You can quote me on that!" Dennis - 2016 3500 Cab Chassis Sprinter - Suspension Package A red rears

" I have driven my Sprinter 50k in 7 months,,, therefore I feel that I have a pretty good idea of its general characteristics. I was excited to get the suspension upgrade (Koni front and rear plus the Sumo springs ) I installed them and had to go out to test them, 80 miles later I returned home . A huge smile on my face the whole time !!! The stability that this caused is remarkable, changing lanes at 80 , passing semis , Cornering, traversing driveways. Super stable . Thanks" Peter in GA - Sprinter 2500 -
