What does the mechanical and systems department cover?
Mechanical and systems services cover electrical, generator, plumbing and appliance work on RVs and working vehicles. Rancho Santa Margarita owners bring units to our Yorba Linda facility, where one crew with load banks, shore simulation and LP instruments identifies the fault before any part is ordered.

This is the department where the money goes into finding out rather than into taking apart. Four services sit here, and all four suffer from the same problem: the symptom an owner reports and the component that failed are usually in different places. A refrigerator that stops cooling can be a gas pressure problem. A generator that will not hold load can be a fuel problem. A wet cabinet can be a fitting three feet away.
So the department is organized around instruments rather than around parts. Load banks, shore simulation, manometers, a decay gauge and a thermal camera exist to turn a complaint into a measurement, and the measurement is what gets quoted. That approach costs an hour up front and it is the reason parts are not thrown at problems here.
Schedule of work
One department, four services, one instrument set
Electrical, generator, plumbing and appliance work all end up needing the same handful of instruments. A no cool refrigerator needs an LP manometer and a thermal reading. A generator that stumbles under load needs a load bank and a fuel pressure gauge. A wet floor needs a decay gauge and a thermal camera. A dead inverter needs true RMS current on both DC and AC.
Splitting those four services across separate crews would mean four sets of the same instruments and four technicians who each know one quarter of a system that is genuinely interconnected. On a coach where LP feeds the fridge, the furnace and the water heater, and where shore power, solar and a generator all feed one bank, that separation would produce worse answers.
- Electrical repair: 12 volt, 120 volt, banks, solar, inverters and harnesses
- Generator repair: maintenance, overhaul and new set installation
- Plumbing repair: fresh water, waste tanks, heaters, fixtures, pumps and valves
- Appliance repair: refrigeration, cooking, microwave, rooftop air and heating
Why this department charges for the diagnosis
Diagnosis here is not a courtesy that precedes the real work. It is the majority of the skill and frequently the majority of the value. Finding the one termination in a coach that is running hot behind a closed panel, or proving that a bank is losing capacity rather than failing to charge, is what makes the subsequent repair correct on the first attempt.
So fault tracing posts at $285 per hour with a one hour minimum, and it credits in full against an authorized repair. An owner who authorizes the work pays for the diagnosis once, inside the repair. An owner who takes the findings elsewhere has bought a documented answer, which is a fair thing to sell and a fair thing to buy.
On cost
Fault tracing is $285 per hour with a one hour minimum, credited in full against an authorized repair. A written repair estimate is $150 on the same terms.
Simulating the pedestal instead of blaming it
A large share of the electrical complaints that reach us begin at a campground or a yard rather than in the vehicle. Low voltage, a reversed pedestal, a tired shore cord and a failing transfer switch all present almost identically to an owner, and the usual outcome is a part replaced on a guess.
The department carries shore simulation supplies at 30 and 50 amp so the vehicle can be fed a known good supply in the bay. If the fault disappears on a clean supply, the vehicle is fine and the problem is upstream. If it persists, we now have a fault that can be measured under controlled conditions. Either answer is worth the hour it takes.
The four services in this group
Electrical repair covers 12 volt house circuits, 120 volt shore circuits, house battery banks and charge paths, rooftop solar and controllers, inverters and converters, and harness and distribution panel work. Generator repair covers scheduled service, overhaul of the head and engine, and installation of a new set with its compartment and exhaust routing.
Plumbing repair covers fresh water lines and pumps, black and gray tanks, water heaters, fixtures and pans, and pumps and valves. Appliance repair covers absorption and compressor refrigeration, ranges and cooktops, microwaves, rooftop air conditioning and furnaces or hydronic heat. Any of the four is a reasonable place to start, and intake will move a job if the symptom points elsewhere.
LP, refrigerant and the hazmat charge
Any gas joint this department disturbs is leak tested electronically and verified with a manometer before the unit leaves, and every gas appliance that runs indoors is checked with a combustion analyzer and a carbon monoxide monitor. That is not an optional line on the estimate. It is the last step of the job.
A $45 flat hazmat and disposal charge applies whenever LP, refrigerant or shop chemicals are handled, which covers recovery, containment and correct disposal. It appears once per visit rather than per item, and on a coach where the fridge, the furnace and the water heater all share one gas run, that is a single charge covering all of it.
Rates, minimums and how the credit works
Labor posts at $260 per hour across all four services. Fault tracing and module work posts at $285 per hour with a one hour minimum. Parts at or under $100 carry 100 percent markup and parts above that carry 35 percent, with sales tax on parts and materials and no tax on labor.
The credit is simple and worth stating plainly. Whatever you pay for diagnosis or for a written estimate comes off the authorized repair in full. What it does not do is disappear if you decide not to proceed, because the work was done and the answer was delivered. That is the honest version of how a paid diagnosis works.
Where systems work hands over to the body side
Water is the usual crossover. A plumbing leak found here will very often have already damaged a subfloor, and that repair belongs to the finish shop. A roof penetration for a new solar array or a replacement rooftop air conditioner involves the roof department for the sealing detail. A generator compartment with cracked mounts is a fabrication job even though the set is a systems item.
There is also a boundary we do not cross. Chassis engine, transmission and brake work goes to a chassis specialist, and factory sealed appliance assemblies, fire suppression systems and certified medical or refrigeration equipment go back to their own providers. We say which side of that line each item falls on before you authorize anything.
The department this runs in
The systems department is the instrument room of the building. It carries Fluke 87V meters and 376 clamps for true RMS readings on DC and AC, a programmable AC load bank, shore simulation supplies at 30 and 50 amp, a stepped resistive load bank for holding a generator at rated output, a city water test stand with a decay gauge, LP manometers and a thermal camera for finding hot terminations behind a closed panel. Labor posts at $260 per hour. Documented fault tracing posts at $285 per hour with a one hour minimum, credited in full against an authorized repair.
Appendix: questions and answers
- Why does the systems department charge for diagnosis at all?
- Because on these four services the diagnosis is most of the skill and often most of the value. Finding one hot termination behind a closed panel, or proving a bank is losing capacity rather than failing to charge, is what makes the repair right first time. It bills at $285 per hour and credits against an authorized repair.
- Can you prove a fault is the campground supply and not my unit?
- Yes, that is what the shore simulation supplies are for. We feed the vehicle a known good 30 or 50 amp supply in the bay. If the fault vanishes, the problem is upstream of your unit. If it persists, we now have something measurable under controlled conditions instead of a guess.
- What does the hazmat charge cover on a systems job?
- Recovery, containment and correct disposal whenever LP, refrigerant or shop chemicals are handled. It is $45 flat and it appears once per visit rather than once per item, so a coach having its fridge, furnace and water heater all touched on one gas run carries a single charge.
- Is generator work billed at the same rate as house electrical work?
- Yes. All four services in this department post labor at $260 per hour, because the same technicians and the same instruments cover them. What changes between jobs is the diagnostic time, and fault tracing carries its own rate of $285 per hour with a one hour minimum.
- Is the one hour diagnostic minimum credited if I authorize the work?
- In full. Whatever you pay for fault tracing comes off the authorized repair, as does the $150 written estimate. If you choose not to proceed, the charge stands, because the work was performed and you received a documented answer you can take anywhere.
- Which of these four services covers a smell of LP inside the unit?
- Start with plumbing repair, because that is where the gas run and its joints sit, though appliance repair frequently ends up involved. Either way the whole run gets leak tested electronically and verified with a manometer, and every indoor gas appliance is checked with a combustion analyzer before release.
