Spreadsheet file
A reusable spreadsheet for tracking daily loads, inverter spikes, charging assumptions, and future expansion without redoing the math every trip.
Use the paired calculator or guide first if you only need a quick decision.
Start with the free worksheetDownload a small sample so you can see how the planning file is organized.
Download the sampleMove forward only when the plan needs to be saved, shared, printed, or reused.
Review access stepsField problem
Daily-load math, inverter spikes, and charger assumptions are scattered across notes, calculator tabs, and old screenshots.
Field-ready use case
Use it during a garage power audit, upgrade quote review, or pre-trip reset when the same load assumptions need to be reused.
Preview
These sample cards show the same kind of sections used in the complete file. The sample download gives you the planning shape without publishing the full product.
See which loads actually move the system.
Fridge duty cycle: measure before final sizing
Laptop + router: separate the workday load
Microwave surge: inverter check, not daily-use guess
Preview 1
Built to show watt-hours, amp-hours, inverter loads, and what still needs measuring.
Compare recovery before adding more battery.
Solar: shade, tilt, controller limits
DC-DC: alternator reserve and cable run
Shore/generator: reset-day recovery path
Preview 2
Keeps solar, alternator, shore, and generator assumptions visible in one place.
Turn the math into an ordered upgrade list.
Add battery only if overnight reserve is the limiter
Add solar only if daytime recovery is short
Reduce loads when one appliance dominates the audit
Preview 3
Helps prevent buying the shiny part before the actual bottleneck is clear.
Inside the file
The file is built around checklists, outputs, and practical use. It is not article copy moved into a PDF.

Good fit
This should feel obviously useful before you pay or request access.
RVers who keep changing loads and want one clean source of truth
People sizing solar or battery upgrades in stages
Anyone who wants to stop redoing the load list from scratch
Skip it if
A useful product page should also save the wrong buyer from paying.
You want a one-time estimate and will not revisit the assumptions.
You prefer the free calculator over maintaining your own reusable planning file.
You are looking for a custom electrical design or stamped engineering plan.
Free vs paid
This turns the free worksheet into a reusable planning file you can update in the garage, on the road, or during an upgrade round.
First answer

Handoff
Free tool or guide
Good for learning the logic yourself.
Reusable planning file
Better when a partner, installer, or future-you needs the assumptions in one place.

Best when you need the first answer and do not need to maintain a reusable planning file.
Open free resourceReusable planning file
Best when the answer needs to be reused, marked up, printed, or handed to a partner or installer.
FAQ
The short version: this is a reusable planning file, not custom installation labor.
Use the access button. The form opens with this planning file already chosen, then we reply by email with the payment link, delivery timing, and download details before anything is billed. Delivered as editable spreadsheet files plus a printable one-page summary.
The listed formats are Google Sheets, Excel, Printable summary tab. The planning file is meant to be reusable, so keep a clean copy and duplicate it for each trip, install, or upgrade round.
Not always. Use the free worksheet if you only need the first answer. This planning file makes more sense when you need a reusable planning file you can mark up, revisit, or hand to someone else.
The file is built as a planning template, not a custom design service. You can adapt it to your rig, but measurements, component specs, and final install decisions still need to be verified against your exact equipment.

Printable binder
$39 · Beta accessThis is the polished, reusable version of the checklist mindset: print it, mark it up, and keep it with the rig instead of hunting through scattered notes.
Field problem
Departure, setup, tank, refill, and seasonal tasks live in too many places, so important checks get rediscovered after something goes sideways.
Field-ready use case
Use it as the rig binder before departure, on camp-arrival day, and during reset days when multiple people share the prep work.
First payoff
Departure, setup, reset-day, and shutdown checklists grouped by system
A working trip binder for the garage or tow vehicle
Cleaner handoffs between driver, setup, and indoor tasks
Less forgotten friction before departure day

Let the roof vote before the cart gets expensive.
Track the parts that steal panel space.
Install planner
$35 · Beta accessThis is for the point where the calculator says what size system you need, but the roof still has to prove it can physically carry the plan.
Field problem
The calculator can size the system, but it cannot see vents, AC shrouds, shade lines, service paths, cable entry, or drill-day sequencing.
Field-ready use case
Use it on the roof, in the garage, or with an installer before buying panels, mounts, wire, sealant, and controller hardware.
First payoff
Roof obstacle grid for AC units, vents, skylights, and cable routes
A realistic roof capacity view
Fewer surprises around shade and cable routing
A cleaner controller and fuse placement decision

Reference file
$19 · Beta accessThis is a quick-reference sheet for safer planning conversations with installers, spec sheets, and your own build notes.
Field problem
Wire, fuse, breaker, and source notes get mixed with forum advice, quote language, and manual pages until the verification trail is hard to follow.
Field-ready use case
Use it at the electrical bay, during quote review, or before energizing a circuit so each choice points back to a source and final check.
First payoff
Quick-lookup wire and fuse references for common RV load classes
Faster spec-sheet sanity checks
Cleaner conversations with installers and manufacturers
A field reference that lives near the project
