Chevyrod I would consider putting a tank on one side and a compressor (or two) on the other side. I have the two small Thompson (Firestone) compressors mounted on the 82 Blazer and they aren't "too" bad.
Travis- On my 77 Cheyenne I have one ViAir mounted in the rear of the frame and it's still too loud. You are not going to like them mounted inside your truck.....
