I did that with Paxton back in 92/93ish, I wanted a supercharger for my truck so I got a group of friends and customers together to be able to buy at WD pricing. Several million dollars in sales later now, so I think it worked out for both of us.
I can't help you for the older trucks, but we will be releasing our 14 on up Silverado kit soon, it will be priced much lower than what's available now.
