Ford F53 chassis handling modification question

my 34' gasser RV is lighter at 17k pounds, but still the Ford chassis (air bags on all four corners). I fab'd and mounted a rear track bar due to a very dangerous tail-wagging-the-dog situation. It has almost eliminated the push from passing semi's and prairie winds. Probably 90% gone. Every RV chassis should have one. Probably more important on the lighter gassers with no engine/transmission to weigh the back end down. A cheap, simple, almost maintenance free mod.
