I have followed this thread and done other research on products that would reduce fighting the wind. Wind gusts are always a problem in the West on the Interstate (especially crossing Wyoming). Without winds my Solera tracks well and is a joy to drive.
What I read has left me in doubt whether the fix should be in the front suspension (as with Safe-T-Plus) or with a sway bar in the rear.
See the document from RV2 website dated Sept. 2012 that discusses all the mechanical issues with swaying.
My buddy at Camping World contacted the wholesalers of the front steering control and he said the manufacturer is now recommending that the solution is in the rear Sway bar. They recommend the Roadmaster Sway Bar, Roadmaster Inc. - Tow Bars, Braking Systems & RV Accessories
I will keep tracking this issue for a while before I install any equipment. Thanks to everyone for describing your experience. Cheers, Steve
