New suspension upgrades

I have a similar story with heavy duty Bilstein RV shocks I bought from Tire Rack and installed myself on our 24 foot 2007 E350. CLICK HERE for write-up with pictures. I was afraid they would increase the harshness of ride, but that was not the case. They simply improved stability. I highly recommend them.

I think the tires are over-inflated. They are higher than the door recommendation which is 68. Two are at 80 and the rest are about 75. But it’s cold outside now so I’ll check.
I’m not fully loaded so have not weighed yet. Maybe it’s the Koni shocks that have contributed to what feels like a more stable ride in high winds. I had only read that the Sumo reduced harshness.
Nice to get input here. This 26’ rig feels bumpier than our 22’. Feel rattled around when riding in back especially on smaller highways. I don’t know if that has improved.

Also install a heavy duty front stabilizer bar and you will be even more stable.

Those expensive Koni-FSD shocks are supposed to reduce tiny road imperfections. Significant road imperfections would be no different than with other heavy duty RV shocks.

As far as harshness-of-ride is concerned, over-inflating your tires is one cause. Having too much load-margin on any axle is another cause.

Our short E350 rig had a very light weighted front axle and an at-load rear axle. I smoothed out the ride up front by swapping front coil springs with ones rated just a little more than the actual max weight. Reducing the weight margin turned out quite nicely.

Generally speaking, adding springs and/or airbags to an existing suspension will increase ride harshness. There are replacement suspension systems like Liquid Springs that replace the rear leaf spring packs, but they cost over $10,000 installed.

I'd love to smooth the ride. I've always been told/believed that shocks help with side-to-side sway and up-and-down 'porpoising', but that shocks won't help with pot holes and feeling every bump in the road. Right?

Are spring upgrades a solution? Running lower air pressure?

Thinking of adding Sumo springs. Maybe they would do more to smooth out the ride.
