The existing bed in this 2015 Mercedes Sprinter is front to back, and I just can't stand it not being across. The mattress is too big to turn sideways, though. Anybody know the right length to order to use all the space across? I'm planning on using several Home Depot buckets as a base, supporting plywood as a platform, with the mattress on top. Anybody order one before and know the right size?
