For touring, well worth the cost. Does not drag the engine down when compressor kicks in. Only uses about 2 1/2 - 3hp. I can only tell when it kicks in as I happen to see the ammeter. At idle at stop sign, you do notice an rpm drop but only at idle. I installed mine working alone without much trouble. Ken Davis is the way to go. Much better reviews than the competition and a lot less expensive. You'll not be sorry if you get one..
