I have driven trucks before and did not expect my older F53 to handle like my Corvettes or my (at the time) Grand Marquis. However, there was room for improvement on my used MH.
The shocks were shot and I replaced them with Koni FSD's. Big improvement on not only sway but greatly reduced harshness over tar strips etc. The rear hung a little low and the passenger side was lower than driver side. Air bags and more pressure on passenger side took care of that.
Lastly, I got an alignment done and was sure to get the caster set to 4-1/2 degrees. Huge improvement with handling/tracking.
Oh yes, I had also gotten 4 corner weights and had the tire pressures set correctly.
Today, it drives and handles fine (for a MH). I have no problem comfortably driving it for long periods. Any F53 will also drive and handle fine if you take care of these things.
