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.
