I just bought this 2006 30" winnebago Aspect e450 and it wandered like crazy. I recently added front Hellwig sway bar, Bilsteins x 4, safety T steering. Tire psi 70/60 R-F. Set rear air bags to 50 psi. This has made a world of difference n driving this rig. I will be installing the rear Sway Bar this week.

Good for you. Once you get the HD rear bar installed, you will have covered your basis. A 30 footer won't ever handle like a tight SUV, but you with have come a lot closer to that ultimate goal. Our 24 footer with 158" wheel base handles quite nicely with all those suspension upgrades.

I have learned over the years that a cruising speed of 60-61 mph is a sweet spot for best-handling which naturally reduces driver fatigue, and also improves fuel economy. At that slower speed, everyone passes us on the interstate highways. I find it especially interesting how the same motorhomes keep passing us at great neck speed. They stop much more frequently so making time isn't working, but they don't realize it.

Just slow down, relax, set the cruise control to 60mph, then burn through your large E350 or E450 fuel tank efficiently. Having a comfortable 6-way adjustable driver seat is another key contributor in driving more than 3 hours at a time.

Add front sumo springs , Rear Hellwig ASB and if you tow or cream on top add in a rear Trac Bar !

I did the all above along with an alignment , only difference I drank the koolaid from reading others posts here on the koni's , I actually felt I went backwards when I put those on !

Those koni shocks are garbage ! There's a reason why the Bilsteins are on back order ! [emoticon]

I am "with you" concerning HD-RV Bilsteins. Reiterating that I am "Extremely" happy with how well the HD-RV Bilsteins manage our 24 foot rig on a 2007 E350 chassis without increasing "harshness of ride". I read mixed reviews from people concerning their personal experience with the Koni-FSDs. They cost a dang fortune. I hoped the extra expense offered a guaranteed sweeping improvement.

Regarding Sumo Springs, I have studied how they contribute. If my choice is either Sumo Springs or Heavy Duty Stabilizer bars, I favor the bars. Maybe having both together would be a perfect union.

Aside from being a weaker bar, the problem with the stock front stabilizer bar up to and including model year 2007, is the design of the two end-link attachment points. The "rubber grommet" design quickly wears into an oval hole introducing inherent "play" in the bar. The stock bar then has no influence until after the rig is in a substantial "lean". You could mess around rotating, then later replacing the two end link rubber grommets, both being short-lived solutions, or spend a lot less time and aggravation and replace the entire design with a heavy duty version that is much more effective and robust.

I have a Chevy Based RV and I would highly recommend Bilsteins
Front Ones

Rear Ones

Made it ride smoother,less lean,more stable and no porposing.

When I replaced the stock shocks (gas charged) with the koni's they were like the old style hydraulic oil filled shocks, I actually had to pull them open to install them. Unlike the gas charged style where you cut the zip tie and work fast to get the bolt through the holes lol !

Once I installed them I went for the test drive , going through the dips the front end dove down more than with the factory shocks.
I called the place where I bought them and talked with them about the shocks and my concern about them.
They said once they were installed no return.
I emailed koni customer service and they just came back with the same literature you'd read in their advertisements about them.
They were no help either.
