- 2 speed transfer case optional now?

  My last three 1/2 ton GMC SLE's had the Z71 package. All of them had the 2 speed transfer case and Auto 4WD. My AT4HD has all of the above standard. In order of use, I use Auto 4WD the most then 4High. I rarely use 4LOW but like having it anyways. My next truck will probably be another AT4HD.

  I have no direct experience, but everything I have seen indicates Silverado and Sierra bed geometry is identical.

  Glad you're progressing well. Keep up the PT and continue to stay in shape after formal PT ends
