I designed my shuttle with this in mind-I have the shower stall directly behind the driver, solidly mounted to floor, chair rail, wall and ceiling, so anything remaining in motion in a front end collision will have to go through that first. It's built from 3/4" veneer plywood.

Similar story behind the passenger seat-fridge mounted in a similarly-constructed and mounted box.
