When I bought my truck it came with a set of train horns, previous owner had the tank and compressor mounted in the bed and also had a topper on the truck. I took the topper off and a month later the the compressor took a crap. Finished rebuilding it last night and trying to think of a good spot to mount the tank and compressor. I'm thinking under the truck somewhere along the frame. Where do yall have yours mounted at? Pics would be awesome because I'm trying to get some ideas.
