Getting back to the forum regarding the sway bar.
I decided with the help of this forum to purchase the rear sway bar directly from Roadmaster. I got the Rear Aux Sway Bar #1139-146 for $821.25 and contacted a RV repair place close to my home (not an RV dealership). As it turned out I had family connections to the owners and it made a comfortable difference in our relationship.
After I got delivery of the Bar, I made an appointment for the installation. It went well, until the tech realized a couple of small parts were missing from the supplied items. I contacted Roadmaster and they got them to me ASAP via USPS Priority Mail. A quick visit finished the job a few days later and Roadmaster covered the minor expense for the second visit. Bravo Roadmaster!
First, I need to recognize well how Roadmaster handled everything, they were professional and provided great customer service, certainly worthy of return business should I decide on more components for my rig.
Secondly, The bar is AMAZING, I can't believe the difference it has made in handling, it drives great, doesn't bob and weave on turns and road variations are minimized. I'll be taking it on the road in a day or two for a fall trip, I'm anxious to see how it handles on a trip. I suspect I'll be pleased with the difference.
BTW, finding this small family owner RV/automotive repair center was a hidden gem to this whole project. They accept extended warranty insurance and are experienced in all areas of RV maintenance. Also, I never heard from the two RV dealers I called and for sure I won't ever be calling them again.
