It might be between the Z71 and ZR2 as far as the off road bits, but the Z71 is more of a luxury trim now and will be priced higher than the Trail Boss.

Fords online configurators have had issues for awhile it seems. It was the same way when the Bronco came out, you could add X option online, but when it came to placing a order you couldn't do it.
