Hi, First I'd like to say Thank you for welcoming to this forum. I just purchased a class C from my sister, which she and her husband did not use much. Its a 1994 Fleetwood, with 30,000 miles on it, 22-1/2' in lengh. It is a Ford 350 with the 460 engine and runs great, looks great and everything works as it should, except for the swaying. It is all stock, but it looks like he did replace the all shocks with Monroe Magnum 285. I have been looking at the sumo springs, but they need a gap or space, so i don't think the all the swaying will be eliminated with these. Not sure if I should change rear shocks and go to a heavier duty type..?Please tell us a little more about the RV and anything that may have already been done to the chassis. Completely eliminating may not be possible but there are things that can improve your handling.
Thanks for the reply. I am looking for a truck shop to get it into, everyone is booked out for 2 to 3 weeksIn my opinion, the first step is to determine if the suspension requires any repairs.
Worn bushings, rod ends, ball joints, broken parts, etc. If the suspension did not receive routine maintenance any one or more of the suspension parts could be causing issues.
If you have a truck suspension shop that you trust, you might have them take a look. I'd avoid a RV dealership unless they specialize in suspension repair.
Next step, after determining the suspension is working as designed, determine under what conditions you are getting unacceptable handling condition. Then address that condition.
Many people guess and just throw money at these problems, it gets expensive and frustrating. Suspensions look deceptively simple, however, vehicle handling is very complicated.
If you are in Florida, Josam in Orlando or Glenn's Tire in Melbourne might be good choices.
