Good point. It is my belief that every E350/E450 comes off the Ford assembly line with fixed camber/caster sleeves which have a caster setting about +3.0 to +4.0 degrees of runtime caster. This setting is good for city vans but should be +5 to +6 for highway driving.

The symptoms of not having enough caster on the highway is looseness in the steering wheel (ie a dead zone between left and right), which results in a lot of wandering and instability.

Note: If the rig has a fore to aft nose down of 1.0 degree then the runtime caster off the Ford assembly line is going to be about +3.0 degrees. Having rear air bags on a completed RV will get you here. If the unit is fore to aft level then the runtime caster off the Ford assembly line is going to be about +4.0 degrees. In either case you want to shoot for +2.0 more degrees caster provided by replacing the camber/caster sleeves.

WDW, here is what was done on the chassis alignment. I don't have the Hellwig specs.
