Initially I put the above listed AFE loops on my frame, but they suck to access in the snow/mud and the strap angle puts pressure on the front bumper. I installed a covert bumper by CBI and have been very happy with it. Accepts a winch, has tow hook connections, has a solid bull bar and makes a great connection to the frame. I think it was just over 1k shipped.
I agree that it's ridiculous that it wasn't an included item, especially with the TRD package.
I believe the CBI covert bumper comes standard on the high end fancy version of the Tundra that's similar to the Raptors and such.
The covert bumper has a great stock appearance and extends a solid metal plate from mid grill line all the way down to the skid plate.
