I'm going to 37's in the spring. Yes on a D30. By then my 35's will be shot. My new gears will be here Monday (5:13), I just installed Teraflex 1" spring spacers, and Alloy USA axles are in the garage. Hopefully by the end of next year I'll have a proroc 44 up front and 35 spline Superior axles in the rear with a ARB.

 

Correction... of course 16mpg and not 26 (typo). That's for my daily commute. On long road trips with heavy load it is more like 14mpg.
