Been fighting an F53 chassis since purchasing it new in 2000. Every seam in the road was like a "3" on the Ricter Scale. Put new Monroe Gas Magnums on it; slightly better but still like a Buck Board. We finally ponied up for Brock's AD-A-RIDE air ride system. Now I understand why the big rigs don't have to slow down while my dash was disintegrating before my eyes. Hands numb from the shock transmitted through the steering wheel, my Ischiums were leaving a permanent impression in the seat! I installled it myself. My only regret is that I let the $1200 hold me back. Now, when I think of it, the diesel pusher owners paid twice the price for an air ride. Seams and pot holes don't bother me now cause I'm floating on a cushion of air--just like the big boys! Now if I can find a similar system for the rear.... Feel free to use my name when talking to Darlene at Brocks; she already knows how I feel AND MIGHT GIVE YOU A DISCOUNT.
