Side elevation drawing of Unit 01 from the curb side, front at left. It shows the high-roof van outline at 290 inches overall length and 170 inch wheelbase, the sliding side door, roof equipment (rooftop heat pump, solar, flat-panel satellite, awning cassette), the shore power inlet, and the battery and inverter location under the intake bench, with the four interior zones mapped below.

Cross-section drawing of Unit 01 at the hearing booth, looking forward, curb side at right. It shows the seated single-station hearing booth beside the aisle, the overhead cabinet on the driver side, and the rooftop heat pump, solar, and awning cassette above. Dimensions show the booth capped at 72 inches against the 79 inch factory standing height.

Electrical one-line diagram for Unit 01, with AC lines solid and 12 volt DC lines dashed. Shore power, rooftop solar through a charge controller, and the alternator through a DC to DC charger feed the lithium bank and an inverter charger. Circuits serve the rooftop heat pump, hearing booth, specimen fridge, outlets, lighting, water pump and vent fan, satellite and router, and the awning and step motors, with a shunt reporting battery state.
