spring relo: offset vs. mini tub for handling?

Interesting. When I was still running my Duster fenders the 225/60/15's cleared at the back, I didn't have to mess with the fender to splash apron bolt like that. But that may have been because I was already running adjustable strut rods and poly LCA bushings at that point, I run the strut rods as short as I can make them without causing any binding. It increases caster, but it might also have given me the tiny bit of extra clearance you guys apparently needed.

If you were still in bodywork stage you could make adjustments to that corner. Mosleyme did that on the front corner of the wheel opening on his barracuda, same idea. Basically you cut a pie shape out and re-weld it. Duster's have pretty tight front wheel openings. Of course I had to do some re-working of my Dart fenders on the front lower corner to clear my 275's (nothing like mosleyme did), but the back isn't even close to being an issue.
