I attended our Bigfoot Owners Club International rally and won a SuperSteer Rear Trac Bar in a raffle. This is an addition I wanted for my 29SL Class C. I also wanted a self centering steering stabilizer. When I called Hendersons Line Up, the lady, answering the phone, was was helpful in setting up an appointment to get both items installed. The company was gracious in suggesting we come in the day before and plug in to their electric in front of their work bays. Our appointment was set for 8am, the next day. I checked in at at 8am. On asking where a good place to have breakfast, they not only said to go to Powder Horn, but pulled out a map and highlighted to route. Henerson's was right on the money. About 1:30 pm, the work was complete and I went with the mechanic on a test run. The mechanic made two adjustments to the front stabilizer bar and it was perfect. Did not know how all this worked until we hit the road and traveled 200+ miles south on I-5 and then took the CA 89 route to Susanville, CA. On the trip I immediately noticed how well the Safety Steer front stabilizer worked. It was like it took about 80% of the wander out of the steering wheel. Steering was very positive and was icing on the cake in driveability. The rear trac bar took the rear end wander out of the mountain roads with curves. I even noticed how stable the rig was when a gust of wind would hit the RV. Between the rear trac bar and steering self center trac stabilizer our Class C remained steady. I need to note that our Class C already had front and rear stabilizer bars and Bilstein shocks. These components work to make our RV a pleasure to drive.Henderson's Line Up performed excellent work with work performed on time. Each person in their shop showed professionalism and genuine interest in their customer. They even gave us two sample bags of candy and a key fob. I will follow up with a letter to Henderson Lineup and a letter to our club president. I also want to thank Henderson Lineup and Supersteer for attending our BOCI Rally in Astoria, OR, and contributing the rear trac bar to our rally raffle. This is a company that is very professional and personable. Thanks. I now look forward to taking our RV out more often.
