I shopped around and waited for a while for any sales. didnt find anything. I did hear that in March is usually when a couple companies start offering the free installs and discounts but I could not wait that long. I found the best price for the Pro Comp kit from 4wheelparts. They had some web promotions and I mentioned those when I called them in person. I am also lucky enough to have a 4wheelparts shop close to me in Raleigh, NC so they did the work as well. I know Pro Comp owns 4wheelparts so that is probably why they had the best price. I didn't know well enough any of the website places to order from so I stuck to ordering it from the shop I knew I was going to have install it.

In regards to your question about the air tank, if you look under the bottom horn you can see the top of the air compressor which sits on top of the tank. Its only a two gallon but plenty of air for both horns.

The hood I got at www.stylintrucks.com Go check them out. I dont do just the scoops unless you fiberglass them on so you dont see the edge of the scoops. I would just get a new hood....
