I sent an email to Skid Row regarding the rear bumper since I got rear-ended and need a new one. Here was their response:

The "plain" rear bumper will have an integrated 2" receiver. However, I'm
not sure when to tell you it will be ready or what it will cost. We're just
going to start working on it again so I'm sure it will take a couple of
months. I'm sorry about that, but I'm trying to be realistic. On the bright
side, the plain rear bumper will be released before the tire carrier so it
won't be as long a wait as it would be if you wanted a tire carrier.
