From the Treklo crew

G'day, we're Treklo

We're a handful of blokes in Geelong who spend our weekends in utes, vans and campers. We got sick of 12V gear that gave up a few trips in, so we started making our own and running it in our own rigs first.

Not sure what you need? Flick us an email and one of us will sort you out. No sales script, just straight answers.

  • We run it ourselves

    Every bit of gear goes in our own rigs before it goes on the site.

  • Out the door today

    Order by 3pm AEST and it leaves Geelong the same day.

  • Sorted here if it plays up

    1 year Aussie warranty, handled by us, not a call centre.
