Calculator link builder
Build a prefilled calculator URL for your exact reader.
A blank calculator is fine on our tools page. A prefilled calculator is better in a forum answer, club newsletter, resource list, or show note where the reader needs a realistic starting point.
Why this exists
Deep links reduce calculator friction.
Use a prefilled URL when you already know the lane: weekend couple, remote-work desert week, water-limited family trip, or a larger stay-length check. The reader can still adjust every input after the page opens.
Use the solar builder when the daily watt-hour assumption is the main lesson.
Use the roof-fit builder when panel dimensions and roof keep-outs are the main constraint.
Use the solar tilt and shade builder when flat panels, winter sun, dirt, or shade explain the gap.
Use the solar string builder when panel specs, MPPT limits, cold Voc, or series/parallel wiring are the lesson.
Use the battery builder when a resource page is teaching load audits or runtime.
Use the lithium-value builder when the lesson is AGM-to-LiFePO4 usable capacity, weight, cycle value, or charger cost.
Use the recharge builder when the lesson is recovery time from solar, DC-DC, shore, or generator charging.
Use the DC-DC builder when the lesson is alternator reserve, drive-day recovery, charger amps, or cable-run pressure.
Use the generator builder when the lesson is run hours, fuel, and generator headroom.
Use the propane and furnace-battery builders when the lesson is furnace duty cycle, cold-weather duration, 12V blower draw, or refill timing.
Use the inverter builder when the lesson is continuous watts, startup surge, and DC current.
Use the tire-load builder when the lesson is scale-ticket axle weight, tire capacity, and reserve margin.
Use the internet-data builder when the lesson is video calls, streaming, updates, background devices, and monthly plan caps.
Use the cost builder when the lesson is free-camping fuel, service runs, fallback nights, generator fuel, or gear payback.
Use the stay-length builder when the real question is which bottleneck ends the trip first.

Resource-page guidance
Pair the link with context, not a hard recommendation.
Prefilled values are useful because they create momentum. They can also be misleading if the page makes them feel universal. Label the scenario clearly, then tell readers to adjust the assumptions for their own rig.
