Chevy/Workhorse P Series Chassis Overview
Originally developed by General Motors and later continued by Workhorse Custom Chassis, the P30 & P32 chassis have been a foundation for many Class A motorhomes and renowned for their durability and reliability. Built on a strong steel frame, the P30/P32 chassis typically features rear-wheel drive, independent front suspension, and heavy-duty components that provide a stable, comfortable ride—even under the demands of large coach bodies. While production ended in the mid-2000s, the Chevy/Workhorse P-series chassis remains a trusted backbone for many well-maintained motorhomes still on the road today.

Steering Play
Steering free play is probably the number one complaint we hear about from coach owners at our shop. This happens when the steering wheel can be moved back in forth in your hands, but the vehicle is not steering. In other words, there is excessive “play” in the steering wheel. When you stop and consider how many different components are involved in the steering action on today’s motorhomes, it’s easy to understand why steering free play is such an issue. You have the steering wheel, coupler, two-three universal couplings, steering gear, sector shaft splines, the pitman arm, drag link, bell crank, tie rod ends and the tie rod end sleeves.
Road Wander
Sightseeing while driving is something we all enjoy, but when your motorhome wanders, it can take the fun out of your journey. You know, you just look away for one second, and your motorhome is on its way out of the lane—it requires constant attention to keep it going in a straight line. We call this issue “road wander”. The John Deere chassis was notorious for it—we used to call it “the wandering Deere”, but that’s another story.
Poor Returnability
Ever since your first car, you probably became accustomed to turning a corner, then letting the steering wheel slip through your hands as it returned to center and the car continued in a straight path. This is what we call “steering returnability”, and if the steering and alignment in your coach is correct, this is how the steering should respond.
