Howard Steering is really nice to have.
My 94 Marathon came with the Howard Steering and it is a really nice system.
Not only does it keep the bus going straight down the highway when you are in a crosswind, it also reduces the steering sensitivity a little so when you are on the freeway the steering inputs are less to keep in the lane. Easier driving.
Once while driving across Iowa with a 60 miles per hour direct crosswind, and I stoppeed and used a wind speed meter to check it, I had the Howard Steering turned on and at it's maximum 120 psi pressure setting. That much wind it could not compensate for, and every time we passeed a truck or were passed by one, there was a large directional excursion as the side wind changed quickly. It made me realize how nice the system was at all other times when it worked just fine. And made me feel sorry for those coaches that did not have it, especially the plastic ones.
When I get off the highway, I switch the system off to make maneuvering in parking lots, etc. easier. The wheel is a little easier to turn with Howard Steering off.
