Scott, actually you could probably build a decent air ride set up from Air Ride Tech for less then $3000 easy. There's also another place that a lot of the board members buy from called Suicide Doors. You could build an air ride setup from them for probably less than half the price of the Air Ride Tech setup.
I've always thought about joining up on the Power Tour, but I'm not sure how far my truck would make it at this given time. I do have it in my things to do list though.
For all your suspension questions, be sure to check out the
Suspension Forum part of the board. You can ask any question on lowering kits an what not, and will get an answer.
Thanks for the props towards my truck. It's got a long way to go, but we'll get there eventually. Be sure to check back on the show guide as it has only started to be written.
Keep us posted on your build.
