I test drove one with out the air and one with and I could definately tell the difference.I went even further and contacted a
member of the Hummer Racing Team via the internet who recommended the Air as well. I'm sorry their name escapes me at this moment. Mine, however is going to be my Daily Driver and will be used alot for work so comfort was high on my list. I was also told Some --- who are into a lot of serious off roading may prefer not to have the air because more can go wrong with it, so you may want to look further into that.The tubular side bars/steps also will bend so that's why I opted with the removable step. Leather is a must and Since they boast about having the largest sunroof I myself would rather that then a after market product. Good luck!!!!!!
