The limited comes with air suspension standard as well as items you'd find in the convenience group like keyless go and automatic headlamps. Just to add to what's already been said.
I chose the limited over the LH as I'm not huge on the cowboy styling of the LH. The limited is basically a LH trimmed out in a more subtle, less cowboyish, manner. Here's my window sticker. It shows what comes in the Limited "26M" package.
