I also found the unit to be surprisingly easy to install. If you take your time and follow the directions, like any other part, you won't have a problem. I choose Old Air because I have never liked the look of a vent running along the base of the dash. They have the option of routing the main vent through the old speaker grill leaving only a vent at each end of the dash.
I was also able to divert my cowl drain from exiting above the distributor to exit into the right wheel-well.
I would buy another unit from them if ever I need one. The truck is in the shop to have the unit charged but I'll post some pics of the whole deal when it gets back.
