Right after the Costa Mesa Overland Expo,
Mark - the owner of Big Slack Off-Road - handed me the keys to one of his trailers and said:

“Go test it.”

That led to my full field test video…
But this video?
This is where we go deeper.

In this episode, I sit down with Mark for a full walkthrough and interview, breaking down the design, the decisions, and the thinking behind this trailer - from the ground up.

If you’re looking for a trailer that blends overlanding capability with real-world utility, this one hits a unique space.

WHAT MAKES THIS TRAILER DIFFERENT

- Inspired by the M416 military cargo trailer
- Built for overlanding AND everyday hauling
- Simple, durable, and purpose-driven design
- No fluff - just function

This isn’t just a trailer for weekend trips…
it’s something you can actually use day-to-day.
