Henderson's put on Koni's, SuperSteer Motion Controls, and a Safe-T-Plus unit on our Monterey after the road test comfirmed what I already suspected needed done. They tweaked the adjustable steering also. It is a whole new rig, and worth the expense.
We didn't have that many miles on it, so the factory Bilsteins were not worn, but I was tired of the excess rebound motion on road dips like you might encounter on Hwy 101 with a sandy base, or with Alcan heaves. It's very slightly stiffer ride now quells that, the motion controls mean it doesn't rock side to side hardly at all, the Safe-T-Plus resists wind effects like it did on our old Pace Arrow and adds confidence re. a blow-out event, and it resists wandering. It should've come from the factory that way.
While you're in Golden, Jeff, drive up in the east mountains and check out the view from the hangliders' jump at the top of Mount 7.
