That's correct. I went to a showroom yesterday and they said it's not on the app. I was especially worried because I didn't get the $1000 email that many did either.
I want the built in ramp but it doesn't look promising. If you look at the mexico trucks with the open tailgate, there is not much more downtravel available before it hits the bumper. I don't see how the extending parts can make up for the remaining downward angle.
I'm in about the same spot as you and I'm hoping by March. I looked at the reservation tracker and about 10% of the first 200 orders are out of country and if that scales to our place in line, those may cancel and move us up.
