Does anyone have any detailed specs/instructions on installing air horns? I'm interested in installing some no my RV and the local service centers here are too busy to assist. I am looking at the Hadleys 'Bully' I believe they are called. Would also consider roof mounted but that is a little much for me to take on, would prefer a 'professional' install. Any feedback on direct-drive electric compressor horns? Thinking they may be an easier install.
