Ford F53 chassis handling modification question

Before you start putting band-aids on, have the alignment checked. Be sure the caster is set to at least 4-1/2 degrees. The alignment people may push back on that, as it is more work than they might care for, but insist.

Between that and putting Koni FSD shocks on, I have no complaints about my "older" F53.

Oh yes, get your MH weighed when fully loaded and adjust tire pressures accordingly. Too high a pressure can result in handling issues and too low is dangerous.
