Passing through Gunnedah

Broken down halfway through a trip? Call us first.

A lot of the vehicles in our workshop aren't from round here. Caravans, motorhomes and touring 4WDs come off the road with a battery that's failed, an alternator that's given up, a DC-DC charger that's stopped charging or caravan brakes that won't play the game.

Call the office on (02) 6742 3500, tell us what it's doing and whereabouts you've broken down, and we'll work out the quickest way to get you going again.

  • Batteries and alternators
  • Solar, DC-DC and 12V systems
  • Caravan electric brakes and Anderson plugs
  • Warning lights and wiring faults

Field service

Truck or machine down on the job? Our field service team comes to you.

Dozers, dump trucks, harvesters, tractors and trucks don't come to the workshop easily, so we go out to them around Gunnedah. Starting and charging faults, wiring and battery isolators, and anything that needs the bench comes back to the workshop with us.

5 out of 5 starsMotorhome fault warning
“Jack was super responsive late on an afternoon when my motorhome had an engine fault warning. More assistance was given on the following day with discussions with vehicle dealerships.
