Here’s how you set up your “rack” (bunk) so you can sleep at night without pitching out onto the floor. First, you stuff some bedding under the outer edge of your mattress so there is a “lip” keeping you from rolling out. Then you add some pillows on the inside so you’re not bumping into the cold steel bulkhead all night. Bill found this secret out a little too late and ended up falling out of one of the upper bunks one night. Ouch. It’s quite a drop and you could break your arm.
