Train horn

Where have y'all installed yours. I have a klienn hk3 and not sure where to mount the compressor and tank.

I have my tank mounted on the frame rail. Hidden by the bedside. Manual fill up, no compressor, literally no spot to put it on my truck and I didnt want it in the bed.

I'm having the same problem too. My concern is getting mud on it.

I don't have a spare under the bed, so I mounted my tank, compressor, and horns all under the bed. The compressor is on a bracket we made and bolted to the inside of the frame rail. Tank is in front of where the spare would be and the horns are right where the spare would be. I just routed the compressor's filter in the cab, under the back seat. Still working fine after plenty of passes through this...

Awesome.

since I'm running 35's I haven't had a spare tire so I went ahead nd mounted them hear facing towards the back of the truck. Air tank is mounted on passenger side frame rail
