3Water heater
Isotemp Slim, mounted passenger side of the box. Two co-primary heat sources rather than a primary and a backup:
- Engine coolant loop, a regular path given the mix of driving and stationary time.
- 120V AC element, the other co-primary, for shore or inverter power.
Idling the engine just for heat is treated as a fuel-inefficient last resort. Coolant lines route along the chassis frame rails, under the composite floor.
4Fixtures
Three endpoints, each on independent hot and cold lines from separate manifolds:
- Outdoor shower
- Sink
- Indoor shower
