I have searched all over for this info but I am trying to figure out what exactly came with these "packages"
I know the luxury was more chrome and a 3rd row seat, but I have also seen some places put down that it came with self leveling air ride suspension? Also the adventure was pretty much just a brush guard and a roof rack?

Can any of you shed some light on this or point me in the right direction?

that's a pretty good list.... but you can't go by the little things....

Major items were chrome and heavy duty billet items such as door plates and interior door handles... found on Lux.

Air suspension was the major thing on Adventure.

All had lockers.

Cloth was even standard... but yet my Base has almost all of the options, brushguard, lights, 6 disc, etc as my wife's Lux.... including leather.

 

I have the Adventure package and have Air suspension, bull bar and tail light guards, 4 roof mounted offroad lights and crossbars. All models came with lockers center and rear plus Traction control. I also thought that all models came with leather interior, at least they did in Canada. Some come with an optional third row seat....

 

What year did the lockers become an option instead of standard?
Did all models come with the built in air compressors?

 

Lockers where always standard and the air compressor was part of the air suspension....

 

Yeah Indy.... cloth was standard and Leather was an option.... same as the H3's.... but you see a lot more H3's with cloth/

 

Are their kits to retro fit the air suspension? What are the best ones?

 

There are a few kits out there....

like this type...
