Start with the floor plan, not the bed frame

The orientation decision came first

A real permanent bed with a regular full-size mattress was one of our four original non-negotiables. But putting that mattress front-to-back would have consumed too much of the van's length. We chose to sleep sideways instead.

That one decision preserved enough longitudinal space for a permanent shower, kitchen, and proper seating and work area. The biggest success was not just a comfortable bed. It was what the bed stopped taking away from the rest of the floor plan.

Apply the principle to your van

A front-to-back bed generally needs more floor-plan length. A sideways bed uses less length, but only works if your finished sleeping width suits the mattress and the people using it. Measure your actual van, wall build-up, windows, and mattress. Different vans give you different options.

• Draw both orientations in the complete floor plan.
• Measure the finished wall line, not just the bare metal shell.
• Check sleeping length at mattress height.
• Decide what each orientation makes possible—or impossible—elsewhere.
