I operated medium duty ambulances all my working life on highways at 80 mph and never had to add any of this aftermarket stuff. A correct alignment was always most helpful.
Keep in-mind that there is a huge difference between an E450 chassis ambulance and an E450 motor home. Nearly every Ford E350/E450 and Chevy 3500/4500 based motor home has a significant frame extension hanging off the back of the OEM chassis. Ambulances are built and limited to the length of the original Ford or Chevy chassis. The frame extension on a motor home messes with handling and weight distribution, often accompanied by a massive over-head bed that protrudes forward of the windshield acting like a sail in reverse direction. You really cannot compare any ambulance to a class C motor home even though they are built on the same basic chassis.
