New member, bought new f350 60" cab to axle single cab with 6.2 gas, had 9 ft. alum. flatbed installed added boxes with hand tools,100 gal. fuel transfer tank and this truck still ride's rough,I mean bone jarring. I've hand several 1 tons eguip the same way over the years. Lower air in back duals to50 psi. My question is will this thing get alittle better will added miles {4800} now or am I just stuck with this ride. Dealer didn't have answer.
