There is a huge long thread on another forum about this, google CHF. It involves moving the sway links to the inner hole on the sway bars, front and rear.
I have done that modification using the extended links on the front ( needed on the 27k) and also had a Tiger or Blue ox, don't remember, rear trac bar installed. It makes the rig less apt to be pushed around by winds and road conditions. It worked well. The height, box shape and weights combined moving up, down, sideways and yaw make these motorhomes hard to drive. When it gets extreme windy it is better to stop and wait as driving is tougher and your gas mileage gets very bad as well, stop and rest and relax. I have driven in 30-40 with 50 gusts without problems now, but it tiring so won't do it for long.
