This site gives you better starting points and clearer diagnostic thinking. It does not replace judgment, manufacturer instructions, local code requirements, or a qualified technician when the risk is real.
Symptoms, descriptions, and photos help narrow down likely causes — and that's genuinely useful. But there are things remote guidance cannot account for: hidden water damage behind a wall, a prior repair done incorrectly, a wiring shortcut from the factory, two separate failures stacked on top of each other, or materials that have swollen, warped, or corroded in ways that change how the system behaves.
A technician standing in front of your rig can see, smell, and test things that a checklist cannot. This site helps you think like a technician before you spend money or call one. It does not replace what a technician actually does.
When something doesn't match the guide — trust what you're seeing.
If your situation doesn't fit neatly into any of the steps, that's real information. It may mean there's a stacked problem, a prior repair that changed how the system works, or a failure that needs hands-on diagnosis. Stop, note what you found, and use it when you talk to a technician.
Most RV diagnostic work is low risk — checking fuses, testing voltage, cleaning a sensor, inspecting a connection. But some situations are not appropriate for remote guidance or owner troubleshooting. If any of the following apply, stop and get qualified help.
RV repairs — especially anything involving LP gas, 120V electrical, or structural components — may be subject to local codes, provincial or state regulations, and manufacturer warranty requirements. What is acceptable DIY in one jurisdiction may require a licensed tradesperson in another.
Always check local codes and regulations before performing DIY repairs. This is especially true for propane system work, 120V electrical modifications, and anything that affects how the coach is certified for use.
Good diagnostic thinking follows a sequence. Guessing at components wastes money and sometimes makes the problem harder to find. The rule that applies to almost every RV system failure is:
Verify power. Verify ground. Verify input / control signal. Then condemn the component.
That order matters. A component that appears dead is usually dead because it isn't receiving power, has a bad ground, or isn't receiving the signal that tells it to run. Replacing the component first — before confirming those three things — fixes the problem maybe 20% of the time and costs you money the other 80%. Work through the sequence first.
The Pocket RV Tech exists to close the gap between "something's wrong" and "I know what to check next." It is built on 21 years of real field experience — the same thinking a journeyman technician applies standing in front of the rig, translated into plain English for the owner who wants to understand their coach before spending money or making a service appointment.
It promises better thinking and a better starting point. It does not promise a guaranteed fix — because remote diagnostics, by nature, can't. What it can do is help you stop throwing parts at a problem and start thinking about it the right way.
