Anybody added air horns to a GMC 3500 D/A?
Thinking about a set of Hadley's with compressor and air tank. The only solution I can see is a Custom made "roll bar" type mount directly behind the cab with the compressor and air tank in my tool box. Don't want to direct mount on the roof. Theese are long, around 25" and 29". Any ideas?
Thanks.....

Mount them under the truck.

I had my Grovers under my old F350. Havent had the GMC long enough to think about mounting them up. I do know that I have a lot less room to play with though.
