Your car, your numbers
Range is what your car honestly does on a full charge, not the brochure number (a used Model Y is ~260). The ~15% overnight draw comes from our own cold-morning testing; drop it if you run Camp Mode warm-weather lean. Every stop below recalculates as you type, and your numbers are remembered for other routes. Estimates assume steady A-road driving. If the maths goes red on a remote route, that's not a bug: it's the route showing you where to charge.

Drive it on the three ideas: arrive at camp with 30%+, charge to 90% before any dead zone, and charge midday, never evenings.
