I'd rather not have to pay for storage and the thing is I often am coming home very late from gigs so to make and extra stop at 2:30AM when all I want to do is climb into bed is not going to happen. I' so lazy that I often leave my gear in my car overnight and deal with it the next morning. That will not be an option at the marina where I will be parking though.
My main guitar is a Strat, thus bolt on neck but the others are not. I will look into the issues regarding the neck joint. Set ups every 6months? You must haul your guitars around even more than I do. I take mine in about once a year.
