Calculator link builder
Send people to a calculator that is already started.
A blank calculator asks the reader to do all the setup work. This builder lets you share one clean OffGridRVHub link with realistic starting values, so the reader can check the example and adjust it for their own rig.

Use it when
The reader already has a specific situation.
If someone just needs to browse calculators, send them to the tools page. If they are asking about a particular trip, setup, or constraint, a prefilled link saves them several steps.
Choose the closest calculator
Start with the problem the reader actually has. If you are not sure, use the decision map first.
Change only the values you can explain
A prefilled link should create momentum, not pretend every rig has the same tanks, loads, climate, or budget.
Copy the URL with a plain label
Tell readers what scenario the link represents, then invite them to adjust the numbers before trusting the result.
Sharing boundary
A prefilled link is a starting point, not a final answer.
Use it for
Sharing an editable starting point when the audience already has a recognizable trip, rig, or planning question.
Do not use it for
Turning one example into a universal recommendation or hiding the assumptions behind a purchase decision.
Tell readers
The link opens with sample values, but they should adjust tank sizes, loads, weather, prices, and gear before trusting the result.
Fast starts
Pick the kind of link you are trying to share.
These shortcuts open the builder with a sensible starting tool. The values are still editable once the builder loads.
Answer a real person
Use this for forum replies or emails when a reader needs a realistic starting point, not a blank calculator.
Build a stay-length linkAdd a resource to a page
Use this for club pages, show notes, handouts, or guides where one specific scenario should open ready to adjust.
Build a solar-sizing linkShare a water or tank limit
Use this when the trip problem is fresh water, gray capacity, black tank timing, or service cadence.
Build a water-planning linkCheck a weight or safety concern
Use this when the useful next step is payload, tires, wire size, generator load, or shore power overlap.
Build a payload-check linkBuild the link
Choose a calculator, set the starting values, then copy the URL.
The copied link opens the calculator with these values already filled in. Nothing is locked. Readers can change every number before using the result.
Make the link feel trustworthy
Pair the URL with context, not certainty.
Prefilled values are useful because they lower the first click barrier. They become misleading when the surrounding text makes the scenario sound universal.
Good link text
Try: Run this five-night water check. Avoid: Click here. People should know what opens before they tap.
Honest scenario label
Name the setup in human terms: two adults, five dry-camping nights, 45 gallon fresh tank, conservative shower use.
Useful fallback
When a reader does not match the scenario, send them to assumptions, starter scenarios, or the full tools page.
More sharing options
Need something besides a prefilled URL?
Use the share kit for citations, badges, embeds, and API links. Use linkable resources when you need a cleaner list for a club page, newsletter, or partner resource section.
