I too use an R10 R&Roller but I keep My Bose Compact and my seat in the van along with Mis's,stands,cables etc. I keep my big Bose,and stands set up in my studio. That way all I have to do is grab whichever kb I want and go. I also bought the shelf accessory for the R10 so one trip does it, no matter where I go.
