Re: Trailair Rota-flex vs. Flex Air???

Well I put the roto-flex on another toy hauler I had and it made a big difference. My current hauler has one from the factory but I'm thinking maybe about going to the flex-air for a little more cush. The reason being is that I use the engine brake and when the engine downshifts its a bit harsh and I'm thinking with the flex-air it will take some of the harshness out of the engine braking when its downshifting.
