Exactly.... If this was done, then the wheels could work on a dually w/a 6-8" rear drop if one dismisses the tire capacity concerns.

I advocate 'safety' when re-building a vehichle & making changes to the suspension. I don't feel the 4x 20" LT rear tires are much of an issue in my app (18ft car hauler w/a 1/2 ton C10 as cargo) but if more payload is possible, the correct load range tires should be utilized (which would kill the 20's for me).
