Probably a long shot. I have a small motor home mounted on a Ford E-350 (van) chassis. The front end tends to wander at highway speed, and it is, of course, subject to buffeting from large vehicles and wind.
A product called Safe-T-Plus makes a shock absorber type of product that they claim helps eliminate drift and other control problems.
I’m wondering if an Dopers have experience with this sort of product, and whether or not it’s worth the expense of having it installed.
