Basement - Underfloor Plan

Reference:

The under-floor of a van has lots of space, but also exposure to dirt, grime, and the issue of freezing cold at times. The goal is an under-floor design that minimizes complexity, minimizes maintenance while maximizing space inside the van.

The under-floor layout needs to accommodate the layout inside the van. Inside, the layout has bunks and electronics on the driver’s side and a kitchen on the passenger side. It is likely that the 4-gallon water heater could be stored on the kitchen side. The plan has A/C and heating on the driver’s side for proximity to the bunk room.
