Caravan Build Planner

Build your caravan setup, one addition at a time.

From the first van you look at to the one you build out, keep every feature, note and weight in one place, and compare them as you go.

Solar, batteries, awning, that second spare you’ve been meaning to add. Add a van as a prospect, the one you’re dreaming about or actually building, and log every mod, accessory and piece of cargo as you go. Tare weight rarely means what people assume, always check with the dealer or manufacturer exactly what’s included, OSCA shows your real Projected ATM as your setup changes, not just the number on the compliance plate.

Log an addition once and see straight away what it’s done to your numbers.

Why it matters.

Building a van for the first time, or your third, means separating what you actually need from what’s just clever marketing. Tare weight catches people out here too, ask exactly what it does and doesn’t include before you assume anything.

Every addition you log stays on record, giving you a full audit trail of how your setup, weights and budget have changed over the years, not just where you landed on day one.
