Trip calculators

Pick the problem. Run the check.

Run the numbers before you buy gear or change a route. Search for a calculator, or choose the trip problem most likely to stop the stay.

Search once, or filter by the trip problem.

One screen, one first check.

Search when you know the tool. Pick a problem when you only know what could cut the trip short.

Choose the trip problem you want the grid to solve first.

Problem:First tripUse when:Check what could send you back to town before packing extra gear.
Problem:Solar or batteryUse when:Build the daily-use list before buying panels, batteries, chargers, or inverters.
Problem:Stay lengthUse when:Check fresh water, waste tanks, propane, cold-weather draw, and reset days together.
Problem:Remote workUse when:Plan signal, data, and backup internet before work depends on one fragile connection.
Problem:Payload or weightUse when:Make sure the rig can carry people, water, batteries, solar, bikes, tools, and the campsite plan.
Problem:Full-time routineUse when:Check the weekly refill, dump, fuel, and fallback routine before committing to a route.

Suggested sequence

Suggested first path: First trip

Start broad. This shows whether power, solar recovery, fresh water, gray tank, or black tank is most likely to send you back to town.

Save the starting point

Not sure which calculator to run first?

Tell us the trip problem and we will send the starting point plus the free planner path that goes with it. Use this when the grid still feels like too many doors.

Stay Length Calculator

Use when you are asking

What ends this stay first: power, fresh water, gray tank, or black tank?

Estimate whether power, water, gray tank, or black tank capacity ends an off-grid stay first.

Load check · 5-8 min

RV Power Audit Worksheet

Use when you are asking

What does my rig really use on a normal travel day?

Map the loads, runtimes, and high-draw appliances before sizing solar or batteries.

Time estimate · 3-5 min

Water Usage Calculator

Use when you are asking

How long will fresh water, gray, or black tanks last with these habits?

Project tank needs and usage habits before your next off-grid trip.

Trip check · 6-10 min

Battery Sizing Calculator

Use when you are asking

How much usable battery reserve does this appliance list need?

Add your appliances and estimate how large a battery bank you actually need.

Trip check · 6-10 min

Solar Calculator

Use when you are asking

How much solar and battery do I need for this daily load?

Estimate panel wattage, battery capacity, and inverter size for your daily power budget.

Trip check · 3-5 min

Campsite Suitability Score

Use when you are asking

Is this campsite still a good idea after access, sun, signal, weather, and services?

Score a boondocking site for access, legal confidence, solar exposure, internet risk, water and dump logistics, weather, leveling, and rig fit.

Boondocking Cost Calculator

Use when you are asking

What does this free-camping plan really cost after fuel, fees, and reset nights?

Compare free camping against paid campground nights after fuel, service runs, generator use, fallback nights, and amortized gear.

Recommended order

Start wide, then narrow the expensive decision.

Start broad

Use the Stay Length Calculator when the trip is still fuzzy. It tells you whether power, water, gray, or black tank capacity deserves attention first.

Check my stay length

Build the load baseline

Use the Power Audit Worksheet before sizing solar, batteries, chargers, or an inverter. Guessing here makes every downstream number wobble.

Start my power audit

Size the system

Run solar, battery, recharge, generator, and inverter checks from the same load baseline so the pieces agree with each other.

Size my solar setup

Check the physical limits

Confirm water, payload, tire load, roof space, shore power, and campsite fit before treating a promising result like a build plan.

Check payload margin

Save the plan

Copy the result links and saved calculator inputs into one trip plan, then turn the final numbers into a worksheet or planning file.
