Roadmaster Experience...
I tried everything in the book from Roadmaster (2 different styles) to Ride-Rite. The Ride-Rite's did NOTHING for me, and after all the testing with the Roadmaster setups, I just coudn't justify it.
Some people have GREAT luck with them, I didn't. The ONLY thing I noticed on my setup was POSSIBLY less wheel hop. I also noticed a more severe lack of control at speed with my camper on.
My solution to the buckboarding was to shave 1 1/4" from the rear blocks-leveling out the truck better. I also play with tire pressures, and I have a special set of Air-Ride bags that differs from the standard, and Rancho RS-9000 all the way around.
Like I said, some people have had good luck from them, but not me in my case. Give the distributer a call, he is friendly and will work with you to find the best setup.
