I have a Winnebago 2003 30B. picked it up for good price with 15K miles. First trip out towing a 16' enclosed trailer with light winds. White knuckle experience for sure. Wife starting to get upset stomach from so much rocking and rolling. Going up a long grade I was passed by 18 wheeler. Next thing I know, I was pushed by the blast of air from passing 18 wheeler right off the freeway down a off ramp. Now I know why this motorhome only had low miles on it. Camping trip great, except the drive.
Did a little research before camping again. Next trip no trailer, did CHF with new poly bushings. Much better handling still 2 hands on the wheel. still not happy with handling, built a rear HD panhard (track)bar for rear of motorhome. Next trip with trailer in tow and medium winds headed for same grade. Here comes a 18 wheeler fast and hard, gripped steering wheel with both hands and prepared for the E ticked ride. WOW,
did not get blown around at all. 1 handed drive the rest of the way to camping spot. The only thing I noticed was on turning the seemed to be a slight lag before motorhome started to turn. Installed front track bar and will see if this corrects that issue.
