2005 F53 vs newer 2015 F53 Chassis

My 2013 handles like a dream. I previously had a 1996 F53. My first thoughts were the wheels must be the difference.

My current coach is built on the newer F-53 (2006) chassis with 19.5 tires. It has handled pretty well for the most part. Trucks would push a little when passing and 30mph + side winds could be fatiguing. When compared to my older Dodge Class C my F-53 chassis also drives great.

When I replaced my factory tires, after 7.5 years of use, with new tires that were 4 months old at the time of installation, I had a lot of problems. With my new tires my MH would follow every defect in the road. Trucks pushed me almost off the road. And, most disturbing, at odd times my coach would dodge left or right. My only change was new tires. I did all of the usual things. I checked and set air pressure. The tire installer set the tire pressure to max tire pressure. That didn’t help so I had my alignment checked. It was still good. Next I added sway, trac, and steering suspension upgrades. They help me tame the worst of my problems but I would still get the occasional dodge at odd times. Finally, after about 1,500 miles and 6 months on my new tires they calmed down and now ride great. And with the suspension upgrades I can now hardly feel when a truck passes and side winds are less fatiguing.

I plan on transferring my suspension upgrades to a new coach if I decide to purchase one now.

Thanks for the info.
