Provisioning & feasibility for overlanders
Know it's doable before you go.
Trailworthy tells you whether a trip is actually possible in your rig — the fuel, water, and time it needs, everything to pack, and what it'll cost. Offline, before you lose signal.

The question nothing else answers
Maps plan the route. Calculators do the fuel. Neither tells you if you can actually pull it off.
Before a multi-day trip into country with sparse fuel, water, and cell coverage, the real question is simple — and unanswered.
Great routes, no reality check
onX, Gaia and friends nail maps and tracks — but say nothing about whether your rig can sustain the trip.
One number, no picture
Dozens of them, all free, each answering a single slice. None of it adds up to a decision.
Rebuilt every trip
The DIY answer — fragile, easy to get wrong, and thrown away before the next trip.
"Can I do this self-sufficiently, what do I carry, and what will it cost?" Trailworthy answers that — in one screen, offline.
How it reads your trip
One honest verdict — with the specific fix.
Trailworthy checks fuel range, water autonomy, and driving time against your saved rig, then gives you a straight answer instead of a wall of numbers.
Good to go
Fuel, water, and time all clear. Pack the list and roll.
Tight — here's the fix
Close on one axis, with the exact adjustment: add a day, carry more water, drive an hour longer.
Not doable as planned
A hard blocker — "you can't make the longest leg on your fuel; carry ~33 L more or plan a stop."
What's inside
Set up your rig once. Plan every trip against it.
Your rig, saved and reused
Tank and jerry-can capacity, real loaded economy, water, fridge, average pace. Enter it once; every trip reuses it.
Fuel range, water days, driving time
The math that matters — range against your longest resupply leg, days of water autonomy, and whether the driving fits your days.
Packing, emergency & trip goals
What to load and how much, a starter emergency kit, and a checklist of the things you actually came to do.
The trip's real cost, per day
Fuel, camps, ferries, an activities and emergency fund — totalled and broken down before you commit.
