I have done the same except for the Sumo Springs, The first time out two weeks ago from Tipp City to Lexington with 20-30 mph cross wind on the way home I have seen drastic improvements with the addition of the road master rear sway bar. I still feel the wind on wide open areas, I would estimate the pull from the semis is much less. I think I got to do some final adjustments to the SafeT Plus stabilizer, I am still pulling a bit, then again with all that cross wind it could have just been wind, I now have a generator issue, need to take it to west chester cummins repair as soon as I get a chance. Replaced the queen and pull out mattresses today, pull out big difference, queen not sure yet.
Secarider - I asked the question of a wide variety of sources over the past yaer and a half. FR said that they didn't think it would make a difference. Ford essentially said the same thing. No one seems to be absolutely certain, but the consensus seems to be that it doesn't make a difference. One person, who appeared to know something about it, said he did know that it would reduce the tuning radius by about 7 degrees. Coincidentally, yesterday I discussed this with a wheel alignment expert who said that it wouldn't make a difference. To date, I've spent $3,500 on ride/steering improvement: rear tracbar, front and rear anti-sway bars, steering stabilizer, wheel alignment and Sumo Springs. While all of this resulted in a moderate improvement, the Sumo Springs seemed to have done the most to control both roll and sway.Please let me know if you discover any revelations. Vince
