The harsh ride on your F53 chassis can be significantly improved with quality gas shocks like Bilstein 5100s, proper tire pressure adjustment, and additional suspension components like anti-sway bars.
Bilstein 4600 is best value upgrade for E-450 Class C with occasional towing. Good balance of comfort and control. Koni FSD offers premium ride quality at higher cost. Both significantly better than stock shocks.
Tire cupping on E450 with straight tracking usually means worn shocks - they let the tire bounce and skip. Replace shocks before new tires to prevent the problem recurring.
Your quad shock installation approach on the F-53 chassis is sound, and your initial 30-mile test showing no harshness is encouraging. The key will be monitoring performance over longer distances and various road conditions.
Koni shocks improve ride quality but minimally affect body roll. Sway bars are what reduce roll. Check if your Fleetwood has sway bars - adding them will make the biggest handling difference.
ZF front suspension on Tiffin Breeze has known shock inadequacy. Koni upgrade from Tiffin helps significantly. If still bottoming, add Sumo Springs as progressive bump stops. Check for worn bushings, ball joints, and verify front axle is not overloaded.
Koni FSD shocks are excellent for the Bounder 35K - they self-adjust for road conditions and noticeably improve ride quality. Bilstein 4600 is a more affordable proven option. Either provides significant improvement over factory shocks. Budget 00-1800 for complete set.
Excellent maintenance approach on your 2016 F53 chassis at 87,000 miles. Your decision to replace the original shocks with Bilsteins and service the Dana Spicer 17060S differential was spot-on timing.
