I added the ez flex to my tt and it made a noticable improvement to my 7500 tt. Bridge abutments were less apparent as well as all bumps in general.
My wifes uncles fifth wheel was due for an overhaul and he purchased it based on my recomendation. He also flipped the axles and removed his worn out shocks. He says the ride didnt change from going with solid equalizer and shocks to the ez flex.
I know its not one if the two you are looking at but thought it was worth mentioning. Please disregard if you dont care/want the ez flex.
