The reason the F53 rides like a bread truck is that underneath all the RV BS it IS a bread truck. Your choice is either to live with it or spend enough money to have bought a DP in the first place to make it ride like one.
It really depends on your annual mileage. Do you want to spend enough money to buy 8 years' worth of gas and CG fees to get a DP-like ride? We decided to drive a bit more slowly, live with the ride issues and actually be able to use the rig, rather than being $10K out of pocket and not be able to use it.
Our annual utilisation was about 2000 miles. It depends on your priorities, I guess.
