"In late September 2011, we took delivery of a 2012 Winnebago Adventurer on the Ford F53 Chassis. During the test drive prior to purchase and the subsequent drive home, the motorhome behaved as expected but there was no wind and we were still on our honeymoon with this new motorhome. About 2 weeks later on a drive home from Salem with lots of wind and rain with heavy traffic, the Adventurer was almost not safe to drive...not by me anyway. Something had to be done with the swaying and constant steering inputs counteracting the sway. It was as if the driver's seat was sitting on a bowling ball! Found Henderson's Line Up on the internet and made an appointment for the Road Performance Assessment (RPA). Once there, we loaded into the Winnebago and off we went with a professional behind the wheel. There is a checklist the crew goes by with a subjective score given to each test on the checklist. The one with the most dramatic results for us was the emergency lane change. This maneuver brought out the worst in this motorhome setting atop this chassis and convinced us immediately the result was not acceptable. Once back at the shop, the list of suggested upgrades was provided and we agreed with their suggestions. They installed a Safe-T-Plus steering control, 4 Koni FSD Shocks, SuperSteer Trac Bar, Roadmaster Anti-Sway Bars front and rear. After the recent purchase of this motorhome, we were not mentally nor financially ready for such an outlay of funds for these upgrades. Having said that, we couldn’t drive this motorhome the way it handled either and we had the upgrades installed. The motorhome now drives like it should. We have driven it about 1,000 miles after the upgrade and truly enjoy this motorhome now. I would drive this unit anywhere and look forward to the trip. We thank Mr. and Mrs. Henderson and their entire crew who worked on our motorhome for their professionalism and courtesy. They made the experience pleasant."
