28" Tire to rocker clearance - Duster

So you already did the relocation using MPP hangers which only have one hole.

See if there is a enough eat to drill a new hole rearward of the one they gave you. Like the rms hangers.

Here is mine moved 1.5" back with RMS relocation boxes and 28's.

Oops, my bad. I should have said MP offset hangers, not relocation. So, no meat there. Relocation is what I actually should have done (10 years ago).
