Please, before you start adding parts/”miracle fix everythings”, get the truck level and properly aligned, slightly toed in and then go drive it. You still might need sway bars or better shocks but you might be able to save the money and take your lady out for a nice paid vacation instead..

Here are my thoughts on this E series caster subject:
Some E350/E450 have handling issues, some do not, the following may explain the difference:
Ford ships all E350/E450 cut aways with identical fixed, non adjustable
caster/camber sleeves, "one size fits all". You can recognize these sleeves because they are keyed and cannot be rotated. They are marked "F8UA-AA 0+.25" on the passenger side and "E97A-CA +0-0" on the drivers side.
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.
So, some RVs have a problem with wandering at highway speeds and some do not have a problem. JMO
