You're looking at $545 shipped to 22407. If you have a tonneau cover over the bed I would definitely mount as much as possible in the bed. You could put the tank, the compressor, and the pressure switches all in the bed, horns can be run and mounted under the frame rails or along the frame rails. If you don't want to put your comp/tank in the bed, you could also just mount them under the bed along the frame. It might take you some time to figure out exactly where you want to mount the stuff, but once you have it figured out, you'll breeze through the install! Thanks!
