[Judge]

Most (not necessarily all) motorhomes over 25 feet built on a E-350 / E-450 / F53 chassis push the limits of the stock Ford suspension (springs, sway bars, shocks, steering damper, etc.). Ford does not know if a shuttle bus, motorhome, box truck or ambulance will be built on these cutaway chassis.

The motorhome manufacturers stretch them and then add more weight and height than the stock suspension can handle. As a result ride quality and handling go out the window.

As others have said, you need to do what the RV manufacturers should have done when they built them. I spent $1500 in upgraded suspension parts (Hellwig HD Sway Bars, Front and Rear Sumo Springs and a Roadmaster Steering Stabilizer) and did the work myself to get my 2018 Outlaw 29H on an E-450 to handle and ride properly..... the way it should have come from the factory so it wasn't a white-knuckle adventure driving it.

I have since moved to a Magnitude Super C on an F-550 Chassis that was designed for these types of applications and have the suspensions for it. I have not had to put a dime into the chassis and it handles and rides like a dream.

There is the CHF (Cheap Handling Fix) mentioned in several threads for the F53. It may fix some or all of your problems but I can only speak to the E-450 and what it took to correct the issues you are also experiencing.
