Lean system profile
Minimal Van or Small Trailer calculator scenario.
This is the profile where habits can beat hardware. The key is keeping inverter use and water expectations honest.
Scenario fit
Best fit
Solo travelers or couples with a small rig, limited roof space, and a low-draw daily routine.
Watch for
Small tanks and limited roof space leave less room for sloppy assumptions, even when daily watt-hours are low.

Crew
1-2 people
Target stay
3 days
Fresh tank
22 gal
Calculator path
Open the calculator that matches the current decision.
Best first tool: Stay Length Calculator. After that, use the other prefilled calculators to check whether power, battery reserve, water, or tank capacity is the real bottleneck.
Open stay-length scenarioBest first pass when you need to know which system ends the trip first.Open solar scenarioUse this when the power harvest and panel target are the fuzzy parts.Open solar payback scenarioUse this when you need to know whether solar saves money or mostly buys quiet power and flexibility.Open solar tilt and shade scenarioUse this when flat panels, winter sun, dirt, or campsite shade may explain low harvest.Open solar string sizing scenarioUse this when the panel count and MPPT controller limits need a cold-weather series/parallel check.Open battery scenarioUse this when runtime, autonomy days, or bank voltage are the main question.Open lithium-upgrade value scenarioUse this when AGM-to-LiFePO4 value depends on usable capacity, weight saved, runtime, cycle life, and charger costs.Open recharge scenarioUse this when the bank size looks fine but recovery time may decide the trip.Open DC-DC charger sizing scenarioUse this when driving days may be part of the refill plan and charger amps need an alternator sanity check.Open generator size scenarioUse this when generator running watts, startup surge, charger draw, or altitude derating may decide the backup plan.Open shore-power load scenarioUse this when hookup amperage, charger draw, and appliance timing decide what can run together.Open generator runtime scenarioUse this when cloudy days or quiet-hour limits make generator backup part of the plan.Open propane runtime scenarioUse this when furnace use, hot water, cooking, or propane fridge operation may limit the stay.Open furnace battery drain scenarioUse this when cold nights may be limited by 12V furnace blower draw before propane or tanks run out.Open fridge solar scenarioUse this when the refrigerator is the critical load and solar has to recover both fridge and house demand.Open AC runtime scenarioUse this when cooling hours, inverter surge, or solar-assisted AC runtime may drive the build.Open inverter-size scenarioUse this when AC appliance overlap, startup surge, or DC current may drive the inverter choice.Open wire-size scenarioUse this when DC-DC charger, solar, inverter, or battery cable length may create voltage drop.Open payload scenarioUse this when batteries, solar, water, tools, and hitch or pin weight may erase the rig's upgrade margin.Open tire-load scenarioUse this after payload math when loaded axle weights and tire capacity need a reserve-margin screen.Open campsite suitability scenarioUse this when the campsite pin needs a pre-arrival score for access, legality, solar, signal, weather, and logistics.Open internet data scenarioUse this when video calls, streaming, updates, and device background traffic need a monthly GB target.Open boondocking cost scenarioUse this when free-camping savings need to include fuel, service runs, fallback nights, generator fuel, and gear payback.Open water scenarioUse this when tank size, crew habits, or refill friction are likely to set the stay length.
