If you install the offset bushing in the upper rear A-arm, how much would that counter the reduction in caster when you set the coach to level with the front axles straight?

Richard,

I have one offset bushing in the rear of Double Trouble and the axles are
level. The max Tom Hampton could get with the correct camber was 1.9 degrees
of caster. The rear is a TINY bit low.

Does the Hubler front end give more positive caster?
