RV feels loose in front end
Hi all, My 2006 E-450 Ford Winnebago Aspect class C with 40,000 miles feels like the front end is loose. It tracks ruts and wanders so that I am always correcting. It has been slowly getting worse ...

If your'e intent on getting the alignment get the readings before you agree to go ahead with the corrections. Anything on the negative side of 0 for a caster reading could cause the described issue...but keep in mind Ford builds a great deal of positive caster into their trucks. It's been that way since the inception of the modern day use of king pins.
For example, when the caster bushings (Ingalls 594) on our E450 were set at neutral the caster was measured at +3.3 to +3.5. Handling improved greatly by getting an extra +2.0 to be +5.3 to +5.5.
Another example our Honda Civic, which has a fixed non adjustable caster, measures about +6.9 degrees.
Since power steering came along high +caster is the norm. The only reason you would want lesseer +caster would be for easier handing in city driving. IMO.
