Along those lines, we hope to buy a bus and use it as a moving van. I thought we would put up a full 2x4-and-3/4plywood wall a foot or two back from the driver, and another about five or six feet from the back emergency door: we would use the back for a bunkhouse and the front for sightseeing. We'll put the upright piano and all of our worldly belongings between the front and back bulkhead walls.
How would you secure THAT mess?
I assume leave a few seats in place to anchor the piano (up, left-right, & front-back), and then some stout connections to the chair rail and floor in front of the front wall ribs? Hoping for advice...
