About
Sourcing, standards and the things we will not claim
If you are going to act on repair guidance from a website, you deserve to know how it was put together and where it stops.
What this is for
CampWrench exists for the moment something stops working and you are a long way from a service center with a three week waiting list. The goal is narrow and practical: identify the problem correctly, rule out the cheap and common causes first, and either fix it or arrive at a shop knowing exactly what is wrong.
Where the information comes from
The guides are built from manufacturer owner and service documentation for RV appliances and systems, combined with established troubleshooting practice for those components. That means component manufacturers such as Suburban, Dometic, Norcold, Lippert, Cummins Onan and WFCO, whose documentation covers the parts that are actually in the rig, alongside coach builder literature where the fault is genuinely coach-specific.
Where a procedure differs by model or model year, the guide says so and tells you to confirm against your own manual. We would rather send you to the correct document than invent a detail that sounds authoritative and is wrong for your rig.
Editorial and safety rules
- Diagnostic steps are ordered cheapest and safest first. If a free check can rule out a $400 part, it comes first.
- Safety interlocks are explained, never bypassed. We will not tell you to jumper a furnace sail switch or a limit switch, because both exist to stop a burner firing without airflow.
- Every guide names the point where a job should go to a certified technician, and says why.
- Content carries a last reviewed date. If it is stale, you can see that it is stale.
What we do not claim
We do not publish user counts, star ratings or accuracy percentages. Numbers like that are trivially invented and impossible for you to verify, and a site that fabricates its social proof has told you something important about how it treats its technical content too.
The only numbers on this site are counted from the content itself: 12 symptom guides and 3 system guides at the time of writing. You can count them yourself.
We also do not display manufacturer logos or imply that any RV or component manufacturer endorses this service.
Corrections
Technical content gets things wrong sometimes. If you find an error, especially a safety-relevant one, we want to hear about it and will correct it rather than defend it. Accuracy on this material matters more than looking authoritative.
