Routing of Wiring & Services

Every electrical and plumbing service is carefully planned and executed to ensure long-term reliability in harsh off-road environments. Wiring and pipework are neatly routed, securely fastened, and isolated from potential damage points. We utilise sealed bulkhead fittings when passing through the floor to mitigate water and dust ingress—critical for true off-grid capability. Additional protection is achieved through K-Flex industrial foam insulation combined with PVC shielding, creating a robust barrier against vibration, abrasion, and rock strikes commonly encountered on corrugated and remote tracks.
