I want to get a small 4 rack unit (SKB SLX) which I can carry on the road. I was thinking of mounting the M5 on it along with other units but I completely forgot about the B2T power supply that it needs which is so damn heavy. Have any of you mounted the power supply on the rack too? What do I do with it? Any ideas? It will be a pain to have another bag or something just for it.
