Know it fits
before you buy

Most fitment guides stop at stock. RigPrint starts there and keeps going: lift height, wheel offset, tire size and the trimming it takes, organized into build tiers so you can plan the whole rig, not just the next part.

  • Platform profiles. Bolt pattern, center bore, lug spec and stock sizing for each generation.
  • Build tiers. Stock, mild and full builds with the tire and wheel combos that work at each lift.
  • Verified RigPrint data. Real-world fitment from owners and suspension manufacturers, labeled so you know what's been proven.

A Promised Home: A promised home for the pets you love.
Incubated by TRNK Ventures

Every pet deserves a promise.

For a lot of older pet owners, the hardest question isn't about themselves. It's "who takes care of them when I can't?" Sometimes family can't or won't, and sometimes there isn't any.

A Promised Home connects pet owners with vetted Guardians ahead of time, so the two can get to know each other and the transition is already planned. It starts on Colorado's Western Slope, with the goal of a nationwide network of people keeping that promise.

Websites, social and IT for small businesses and restaurants

Most people check you out online before they ever walk in. Are you open? Where are you? What's on the menu? Your site should answer all three in a few seconds, on a phone, without anyone pinching and zooming.

We build those sites and handle the tech behind them, and we come at it from the kitchen side, not just the tech side. Brian is a trained chef with a career in restaurant operations and foodservice sales, and he builds and runs the websites, domains, email and hosting behind every TRNK brand himself. So we know a menu has to be easy to change when prices move, and that the hours on Google have to match the ones on the door.

In development · RigFlow CRM for Businesses

One place to run your sales and your clients

RigFlow is the CRM we built to run our own companies. Leads, follow-ups, client requests and contract dates sit in one place, so nothing lives in a notebook, a text thread or somebody's memory.

We're running every TRNK business on it first. Once it has earned its keep here, we'll open it to other small businesses. RigOptics, its data sourcing feed, is being built alongside it.

About TRNK

Built by a guy who actually wrenches

TRNK Ventures was started by Brian "Trunk" Williamson, Founder & CEO. He has spent more than 20 years in tire, wheel and aftermarket distribution, from running a distribution center to leading regional wheel and aftermarket sales out of Denver, and he has turned wrenches on vehicles from every decade RigPrint covers.

He is also a trained chef with a career in foodservice, a brewer, a fabricator, and a boat captain since 19. Brian grew up in Indiana, spent 15 years in the Carolinas, and now calls Colorado's Western Slope home, with the San Juans and Moab as his backyard.

That mix is why we build the way we do: real data, real trucks, and tools that answer the questions people ask at the counter.
