Disappointing test drive

I wonder how much of the handling problems are subjective. I have an old P-30 chassis with IFS and when I first bought it, it was a white knuckle ride home, after several months of driving I drove it like a car with one hand even with passing trucks. When looking for a newer MH all were on the Ford chassis with the straight front axle and other than getting used to the higher revving engine noise the ride was fine. I test drove about 8-10 over the years and never noticed a white knuckle ride. Having said all that all the Fords were 2-3 years old and only one was brand new. I felt the cracks in the road in each MH as well as DP's and HD trucks I drove in. I read on here about all the add ons of track bars, sway bars etc. that are needed to tame the ride of the F-53 chassis and wonder if we expect too much from a spring suspension truck chassis.
