2011vs2012 ground clearance etc. changes..... Very interesting
 

I was comparing 11 vs 12 brochures most notably 4x4 screw 6.5 ft box
157" wheelbase
This is what I noticed was different 2011 on the left 2012 on the right
Dimension G- Angle of approach- 23.9/25.8 degrees
Dimension H-Ramp breakover angle- 13.9/15.4 degrees
Dimension I- Angle of departure- 23.8/24.7 degrees
Dimension J- Load floor height- 33.6"/34.5"
Dimension K- Ground clearance- 8.1"/9.0"

Anyone know what they changed on the truck to come up with these differences??

Wheel size?

Thats actually a decent amount there!

No both have a std size of 235/75/17

I find that odd. I have a buddy with a 2012 SCREW 5.5 FX4 and it sits identical to mine. Of course with my supersprings on the rear I sit a little higher. Very interesting though.
