A walk through the Suite: search, brand-specific diagnostics, meter values from the manual, fault codes with their source, calculators, Field Mode and offline use.

Not a mockup. This is a schematic from the app.

The Furrion Chill HE single-zone wiring diagram as it renders in the Suite: fan motor, compressor, run capacitor, heating element and limit switch, the digital control board with its relays, sensors, LED and every connector, redrawn from the factory diagram. Zoom in, drag around, and tap any wire to light up its whole run.

From the schematic library inside the app.

Every number shows where it came from.

Most RV information online is a guess with confidence. Here, every spec, code meaning and test value is checked against the manufacturer's own documentation before it ships. What can't be confirmed is labeled. What fails the check doesn't ship.

Starts at the source

Factory service manuals, install guides and recall notices, the same documents the manufacturer gives its own service network.

Checked against the page

Our words, their numbers. Every spec and test value is traced to the manual it came from.

Labeled, not hidden

Factory-confirmed content reads clean. Anything less carries a colored label in the app that says what it is.

Re-checked every release

Over 40 automated accuracy checks run before each update. Content that fails is pulled, not published.

Factory-verified against the manufacturer's manual. Most of the library.
Scan-verified from manuals that only exist as scanned pages.
Manufacturer-published current information, not yet archived.
Tech-attributed field knowledge, with the source named and dated.

What a working tech reaches for, in one tab.

657

Diagnostic flows

Interactive flowcharts that branch on what you're seeing in the bay. Brand-aware paths route you to the right test for the right unit, then to the procedure that fixes it.

2,043

Error codes

Each mapped to its meaning, likely cause and the fix, with 932 field-confirmed known issues and 848 procedures linked from the flows you're already running.

3,250+

Measurement specs

Pass/fail cards for the ohms, volts and pressures that decide a diagnosis, with the condition, the tool, and one-tap "tests good / tests bad" routing back into the flow.

570+

Model lines across 130+ brands

Pick the brand on the data plate and the flows, codes and specs narrow to that unit. Wiring schematics are redrawn as clean, traceable vectors: pan, zoom, and tap a wire to light its whole run. That library grows as each page clears verification.

Looking up one code? The free error code lookup covers every system; the diagnosis behind each code is in the app. Also inside: 162 TSBs and recalls with NHTSA campaign numbers, 2,174 catalogued components, 10 field calculators (wire and voltage drop, battery bank, solar, propane, generator sizing), and an offline install for iOS, Android, Windows and Mac.

One tool that pays off for the bay and the books.

Questions before you start

Do I need a card to start the trial?

No. Create an account and you're in for 7 days. If you decide to keep it, you add a card then. If you don't, nothing is charged.

Does it work without a signal?

Yes. The library installs to your phone, tablet or laptop and caches on first load, so it works in the back of the lot, under a slide-out, or in the cell-dead corner of the shop. You need a connection about once a week to re-verify your sign-in.

Is there an Android app?

Yes. RV Tech Suite is on Google Play. Install it, sign in with the same account, and it works offline like the browser version. An iPhone and iPad app is coming soon to the Apple App Store; until then, use it in your browser on any iPhone, iPad or laptop.

How do shop plans handle technicians?

The service manager adds each tech by name and email, with a starting password if you want one. Each tech gets their own login; the plan covers the seats. Remove someone and the seat is free again.

Can I cancel?

Any time, from your account menu. There's no contract. Your access runs to the end of the period you've paid for.

What's not covered?

Engines and transmissions are out of scope by design. This is the RV side of the unit: climate, power, water, structure, running gear, and the tow-vehicle detection circuit. See the full list below.

All 40 systems. The brands on real work orders.

Counts are computed from the live library at every release, so what you read here is what's inside.
