1. Inspect the Base Vehicle
Start with mechanical condition, roof leaks, rust, body damage and payload capacity. Fixing the shell after cabinetry is installed is far more difficult than addressing it in an empty van.
2. Freeze the Floor Plan
Confirm bed orientation, galley length, refrigerator position, seating, bathroom strategy and storage. Then locate heavy items such as batteries and water tanks with weight distribution in mind.
3. Cut Openings Before Interior Finish
Roof fans, windows, shore-power inlets and other exterior penetrations are easier to install before finished walls and ceilings. Follow the component manufacturer’s instructions and protect bare metal after cutting.
5. Insulate and Close the Shell
Choose insulation based on climate, moisture behavior, installation method and available thickness. Avoid creating inaccessible wet areas or crushing materials in ways the manufacturer does not recommend.
6. Install Furniture and Fixtures
Build cabinetry around service access. Pumps, fuses, valves, filters and electrical terminals should remain inspectable rather than becoming permanently trapped behind finished panels.
7. Commission the Van
Before the first long trip, test charging, outlets, lights, water flow, drains, ventilation, latches, fasteners and emergency access. Drive a short route and listen for movement or vibration that did not appear while parked.
