Lux package should also have chrome door sill steps when you open the door vs. black--not sure on the '03. I also think they got shiny interior door handles as well?
On the Adventure, you'd have an air suspension button on the dash below your trailer tow & locker buttons, plus a scrader valve/power switch inside the back hatch when you open it on the right. Air suspension could be ordered on a lux package as well though.
I sold that set of steps yesterday, finding a set like that new in the box is becoming hard to do unless you're willing to pony up big bucks (yeah, more than I asked!). I'm always on the lookout for stuff, so if I come across any more, I'll let you know. My wife had back surgery right when we bought our 2, so she couldn't even ride in it until I got the steps.
Anyway, welcome and enjoy!
