I have a 2004 Southwind 37C on Workhouse chasis with 8.1 litre engine. When I am stopped, this thing rocks from side to side quiet a bit when just a car is passing. What can I do to keep it from rocking so bad. Does anyone have any idea what the fix would cost. When I hit a dip on one side in the pavement, it will rock 2 or 3 times . Any info will help. Thanks in advance

How old are the shocks? If original you are over due changing and up grading to better shocks.

Yes, it sounds like the shocks are worn out.

This is a 2004 model southwind. I replaced the shocks in 2007 with Bilstein shocks. Thats not saying they could not be worn out though

If the chassis was made before September of 2003 the W20 and W22 chassis had a 2 inch front stabilizer shaft. Often called an anti sway bar. In September of 2003 WH changed to a 2.5 inch bar.
If your chassis has the 2 inch bar I would strongly recommend that you have the 2.5 inch bar installed. I did and it made a huge improvement in roll or side to side sway.

This is from an email I got from WH in 2005:

"The part number for the Front Stabilizer Bar with Brackets is: W0005643.

This bar was found to have an advantage over the original 2" bar, and was
put into regular production on 9/2/2003.

The installation is very straightforward. Remove 4 retaining nuts while
supporting bar, remove bar, hold new bar in position, reinstall 4 retaining
nuts, and torque to specification. This procedure is NOT meant to replace
the service manual, but is a generalized procedure.

The upgraded stabilizer bar has been shown to provide the following
benefits:
1. Reduced Body Roll when cornering.
2. Reduced "rocking" when passed by or passing large vehicles.
3. Reduced "rocking" when traversing bumps on an angle."


The installation procedure is below- I did not raise the coach, just crawled under it:

Stabilizer Shaft Replacement (Front) (W20/W22)

Removal Procedure
1. Raise the vehicle on a hoist
2. Remove the nuts and washers from the stabilizer shaft clamp and the right front leaf spring.
3. Remove the nuts and washers from the stabilizer shaft clamp and the left front leaf spring, and remove the stabilizer shaft from the vehicle.
4. Remove the clamps from the stabilizer shaft.
5. Remove the insulators from the stabilizer shaft.

Installation Procedure
1. Install the insulators to the stabilizer shaft.
2. Install the clamps to the stabilizer shaft.

Notice: Refer to Fastener Notice in Cautions and Notices in the WCC Service Manual.

3. Install the washers and nuts to the stabilizer shaft clamp and the left front leaf spring.
4. Install the washers and nuts to the stabilizer shaft clamp and the right front leaf spring.

Tighten
Tighten the stabilizer shaft clamp nuts to
373 N·m (275 lb ft).
5. Lower the vehicle.

My 06 Winnebago has rocked since the first day as a brand new coach.When I pull out of a service station or any place where the pavement is a little uneven it nearly throws me out of the seat. Had my shocks checked after i had had it about 3 months and the man said they were still like new. Winnebago claims it's because it is so high and I do not have enough load in it.

I would start with new shocks, it's obvious your rig needs them and that may do it for you.

You might want to take a look at the Roadmaster site and investigate the rear sway bar. That just may stop your rocking. Estimate I'm guessing in the $1100.00 range?
