Just brought home our new Forest River Forester

Harvard and j-d,

You're both hitting at an important issue that would affect caster in Ford's E-Series Twin I-Beam geometry.

My E450 MH has never had a tracking problem in it's steering .... BUT it does sit just a tiny bit high in the rear due to it's rear suspension being plenty stiff for the weight it's carrying back there.

That slight forward rake may point to my caster effectively winding up a bit higher than on some Class C motorhomes that sit either level, or lower, in the rear.
