Yep, starting in 1st on Big Blue is only for when you are stopped on a serious angle and want to make sure you don't kill it. But you'll have to shift into 2nd in the middle of the intersection.
Try it in low range on the t-case! My favorite story is when we were pulling the old sign down at the church building. It put it in low/low, came out on the clutch and walked back asking the guys if they needed help. They stood there with their mouths open as BB just idled and pulled the sign down - w/o a driver.
