On the topic of Ford E450 alignments:

Ford ships all E350/E450 cut aways with identical fixed, non adjustable
caster/camber sleeves, "one size fits all".

The RV builder almost never changes the Ford sleeves, as a result:

If the final RV build is nose down one degree then the runtime caster will be about +3.5 degrees. These units can have a real wandering problem.

If the final RV build is nose level then the runtime caster will be about +4.5 degrees. These units are probably indifferent.

If the final RV build is nose up one degree then the runtime caster will be about +5.5 degrees. These units are probably just fine, possibly excepting the 31 footers.

So, some RVs have a problem and some do not have a problem. JMO.

If too little caster exists, the car will wander and weave,
thus necessitating constant corrections in steering.
