Wandering couch on the road.

I've done a lot of improvements on my '99 36ft. MDS in the last 6 months especially right after the FMCA rally in Pomona.New shocks,new Michelin tires,Henderson motion controls,new master cylinder,safety steer, alignment,etc.I still get a left to right wandering on the highway even without a windy day.The only thing I haven't done yet is change the power steering hydraulic oil which I will do soon, my question is if there is an adjustment on the steering box to remove excessive play in the steering and if this could be part of my problem or could it be something else.Any input would be helpful.

Most roads have a "crown" in the center which affects the steering. You should verify that it stays straight while going through a large level parking lot like Walmart or similar that appears to be perfectly level.

If it doesn't drift right then it's just the crown. Otherwise, you may want to check the "camber(?)" on the front axle. I had my alignment performed by Redlands Truck & RV who used special shims on the axle to get the alignment correct.

Assume you have a Sheppard steering box. Slack is not adjustable without rebuilding/blueprinting.

Have you verified ride height? Ride height in front affects CASTER and caster is important to proper tracking.

What tire pressure are you running?

Check your weights and adjust tire pressure accordingly from Michelin's tire chart. Mine wandered when I got it with the tires inflated to max. Corrected the pressure and now it's straight as an arrow.

Does it pull all the time or just when another vehicle passes? All cars and trucks have different aerodynamics and affect other vehicles as they pass. Sometimes a car feels like it's pushing me but then a large truck can pass and I don't even notice a pull or push. If your new to driving a rv you may want to give it some time these things are still big boxes rolling down the highways it can take some time to get used to the way they handle.

I bought an 2002 34' new from the dealer. The thing wandered all over the road. Checked the tire pressures. The service guys had inflated the tires backwards. You need 110 lbs in the front and 95 lbs in the back. My manual and the placards specified this pressure combination. No more wandering after going with the WRV instructions on front and rear pressures. I am on my 4th Alpine and all of them worked better using WRV's specification on pressures.

The WRV recommended tire pressures ASSUME each axle is loaded to its GAWR (Gross Axle Weight Rating). I would be very surprised if your 34' is even close to GAWR's.

Have you weighed the wheel positions (better) or axles when loaded as you travel?

These big wheeled boxes have poor aerodynamic characteristics that very hard to change. Our 32' Georgetown was real squirrelly and needed almost continual small corrections. It was real hard work.

I mentioned this to another A-gasser owner, and his recommendation was to let it wander some and only make corrections for bigger swerves. He also recommended tire pressure corrections.

I found that the wandering got less when the tires were inflated for the actual weight they were carrying, and minor deviations (a foot or so) were OK to leave alone. Travelling became a lot easier.

When I read the title, I thought you'd found some furniture on the roaad!

Check for ball joint wear on drag link & tie rod (if you meant coach).

My couch also wandered some & tipped if someone say right on the edge; it wasn't bolted to the floor. Bolted now, no more tipping.
