I had the simialr problem getting both packages, I had to order it and wiat for 3 months. I have driven both, I feel that I peffer the truck with both, the ride in the just lux pac is better less bumpy, but the ride with the adventure pac is more sporty and the bumpyness is minimal, it just feels more tight. I love mine and would not have it any other way. By the way the leather seats suck up the bumps better then if you just order adventure pack with the cloth. Hope this helps
As to where or not you will need the off road suspension WHY GET A HUMMER WITH OUT IT> I probably will never push mine to the test but it is a great ride firm and sport like.
