I have a friend who rigged up a RnR type cart with a speaker on the bottom and an inverted hard case affixed to the top ... he retro fit the KB to 'hook' into the hard case so it doesn't move during transport ... everything is wired up and he screwed a goose neck to the case for his mic ... he uses a van in which he hooked up a winch to get the rig in and out ... easy transport and set up for any gig ...
