On my coach they put good strong shocks and good strong SWAY BARS.
My coach is built on a Workhorse chassis and Workhorse knew it was going to be a motor home..
With A Ford Chassis.. I'm not so sure they know what it is going to be when they build it.. I would inspect the shocks to see if an upgrade is in order
But also check the sway bars They too may need an upgrade
One thing I did need to add to my RV, and this would apply to most if not all other chassis makers as well, is a Track Bar.. This applies to all vehicles with solid axles front and rear. Mine is a front one, I'm told rear is even better, (Will add later) but man does that, and a steering stablizer, make a big difference. How big
Well one 2,000 mile trip when I got there driving the towed was a relief
Then I did the work
Next 2,000 mile trip (Same place) Dang that towed was hard to drive when I got there.. Same towed, Same exactly.
