Why I built SK Maps

By Chad, founder · October 21, 2026

I’m a software engineer who rides ADV and takes the truck out overlanding and camping. I wanted one map that works for both, so I built it.

The itch

Out on a Forest Service road, I wanted to know what the road was and whether my truck or my bike belonged on it. Unless someone had written about it, I couldn’t tell. Now you tap the road and it says.

Planning

I wanted to see the hard line and the main line together. Instead I redrew the whole route every time I wanted to try an alternate. That became forks and options.

The rally

At a rally they handed out GPX files, and the same questions kept coming up, for me and everyone riding with me: how much further, how steep, how long to lunch, what does that alternate add? So I put the answers on the route.

The campsite

Passing campsites on a loose Forest Service road, looking for where to sleep, I wanted to mark them without letting go of the bars. So it works by voice, signal or not.

Every feature started as a real moment

The rest came the same way.

Whole state offline: Losing signal. Boxes drawn around a ride don’t cover the day you actually ride.
Logging areas: The convoy on the alternate. A road I’d driven before, full of logging trucks that day.
Buy it once: Paying every year. I wanted to own my map, not rent it, so you can buy this one once.

There’s no single dramatic reason. It’s built out of real days of riding.
