Caravan & RV Wiring Toowoomba
Dual battery systems, tow vehicle wiring, Anderson plugs, DC-DC chargers and 12V caravan electrical setup — done properly before your next trip. Mobile service across Toowoomba and the Darling Downs.
12V Auto Electrical Setup for Caravans, Camper Trailers & 4x4s
Getting a caravan or camper trailer wired correctly means more than bolting in a second battery. The tow vehicle’s charging system, the cable run to the van, and how the van’s own battery, solar and 12V circuits work together all affect whether your setup actually holds charge on the road.
We handle the 12V auto electrical side of caravan and RV setup — wiring, batteries, charging and towing electrics. For fixed 240V mains wiring inside a caravan, Australian regulations require a licensed electrician, so we’ll point you in the right direction for that part of the job if needed.
