How a fitout runs

Four stages. You sign off before the drill comes out.

  1. 01

    Measure & talk trip

    Bring the vehicle to Ultimo for 30 minutes. We measure the load area, weigh up your fridge, water and recovery gear, and work out what actually needs to live in a drawer.

  2. 02

    Spec sheet & fixed quote

    You get a one-page spec sheet: materials, runner ratings, battery capacity, charger amps, outlet list and a fixed price. Nothing changes without a new sheet.

  3. 03

    Build & fit in bay

    Cabinetry is cut and assembled on the bench, wiring is loomed and labelled, then the whole lot goes into your rig. One to four days depending on scope.

  4. 04

    Sign-off & shakedown

    We load-test every circuit, torque-check every anchor, then walk you through the system. Book a free re-torque after your first trip — corrugations find everything.
