RV Trouble?
We’ll Come to You.
Mobile RV repair and diagnostics for electrical problems, RV air conditioners, furnaces, water heaters, plumbing, slides, leveling systems, awnings and more. We diagnose the problem, explain what we find, and help you understand your repair options.
What do you need help with?
You don't need to know which component failed. Tell us what the RV is doing and we'll determine the right place to start.
Mobile RV Diagnostics
Electrical, A/C, furnace, slide, leveling, plumbing, water-heater and appliance symptoms should start with testing—not a parts guess.
Request repair or diagnosis →Independent RV Inspection
Document the visible and accessible condition of the RV before you complete the purchase, with photos and a professional digital report.
Explore inspections →RV Tank Rescue
Get help with buildup, odors, slow draining, and inaccurate tank readings through professional mobile tank cleaning.
Explore tank cleaning →What should you compare before choosing an RV technician?
Price matters, but so does how the problem is diagnosed, how clearly the findings are explained, and whether you understand what you're authorizing.
| What to compare | MilTech RV approach |
|---|---|
| Troubleshooting | Diagnose the affected system before recommending parts whenever practical. |
| Authorization | Explain findings and repair options before additional work is performed. |
| Mobile service | We come to the RV at an approved campsite, RV park, residence or storage location. |
| Customer education | We explain what failed, what we tested and what you should know about the system afterward. |
| Documentation | Service findings and repairs are documented as appropriate to the job. |
| RV-specific training | NRVTA-trained RV technician, NRVIA Certified RV Inspector and Lippert technician training. |
| Pricing | Starting service-call, diagnostic and labor rates are published on this page. |
| Scope | If the repair belongs in a dealership, chassis shop, body shop or specialty facility, we'll tell you. |
Independent troubleshooting matters.
We don't get paid to sell you a particular brand of RV, appliance or repair part. Our job is to determine what's happening with your RV, explain what we find, and help you understand the available repair options.

Repair & diagnostics
Maintenance & travel
Inspections & follow-up
Training & group service
Small maintenance issues can become expensive RV repairs.
Sealant, electrical connections, appliances, holding tanks and other RV systems change with age, weather and use. Regular checks can help identify developing concerns before they cause larger problems.
Roof & Sealant Checks
Inspect accessible seams, roof penetrations, vents, skylights, A/C mounting areas and exterior sealant for cracking, separation or deterioration.
Winterization & De-Winterization
Prepare freshwater plumbing for freezing temperatures or return the system to normal operation when camping season begins.
Tank Cleaning
Address buildup, odors, slow draining and inaccurate tank-sensor readings with professional holding-tank cleaning.
Preventive System Checks
Check the operation of selected RV systems and identify abnormal behavior, visible deterioration or maintenance needs before the next trip.
Know what you're buying before you own the repair list.
MilTech RV provides pre-purchase inspections with documented observations, photographs and digital reporting of visible and accessible RV systems and components.
Essential Safety
A focused safety and condition review for buyers who need a more limited inspection scope.
Advanced Buyer
A broader pre-purchase evaluation covering major RV systems, roof, moisture screening, plumbing, LP-accessible areas, appliances, slides, leveling, undercarriage and more.
Elite Diagnostic
Expanded diagnostic evaluation for buyers who want a deeper look, including additional testing where applicable.
Real RVs. Real diagnostics. Real repairs.
A symptom tells us where to start. Testing tells us what is actually wrong.
Bathroom leak and roof maintenance
Concern: Water leak in the bathroom along with roof-sealant maintenance needs.
Finding: The bathroom leak was traced to a failed sink drain assembly. Roof-vent sealant was deteriorated/separated, and the solar-panel mounting areas needed additional sealing attention.
Repair: The failed drain assembly was removed and replaced. Deteriorated roof sealant was removed, the area cleaned and fresh RV roof sealant applied. Solar-panel brackets were inspected and additional sealant added where needed.
Auto Level stopped with a Jack Timeout
Concern: The automatic leveling system would not complete an Auto Level cycle, although the jacks could be operated manually.
Testing: Auto Level stopped at a Jack Timeout and the displayed level reading did not change. Wiring/continuity checks did not identify the problem.
Finding: Testing supported a failed leveling sensor. Replacement of the sensor was subsequently authorized through the warranty process.
Propane odor traced to the tank valve
Concern: The customer reported the smell of propane in the RV.
Finding: A leak was confirmed at the permanently mounted propane tank shutoff/service-valve area.
Next step: The propane system was disabled. The repair required safe tank evacuation and valve replacement, followed by pressure/leak testing before the system could be returned to service.
An estimate isn't the same thing as a diagnosis.
An estimate based on a customer's description can provide expected pricing for the work described. It does not confirm what caused the symptom.
Estimate
An estimate is useful when the requested work and required parts are already known. Pricing may be based on information, photos, model numbers or a clearly defined repair supplied by the customer.
Diagnostic Service
Diagnostic service is used when the cause is not known. The technician tests the affected system to determine what is actually happening before recommending the next repair step.
“My RV air conditioner won't start.”
That symptom could involve incoming power, a breaker, wiring, controls, thermostat, capacitor, fan motor, compressor or another issue. The symptom tells us where to begin testing. It does not tell us which part should be replaced.
Diagnose. Explain. Authorize. Repair & Educate.
Replacing the most obvious part isn't the same thing as finding the cause. Our process is built around testing and communication.
Diagnose
Test the affected RV system and narrow the problem to the likely failure whenever practical.
Explain
Review what was tested, what we found and what repair options make sense.
Authorize
You approve additional repair work before we proceed.
Repair & Educate
Complete the authorized work and explain the system, repair and what to monitor afterward.
Aron & Sheryl Jemison
MilTech RV is a husband-and-wife mobile RV service business. Customers often interact with both of us before, during and after a service appointment.
Aron handles diagnostics, inspections, repairs, technical research, documentation and customer education. He is a retired U.S. Navy veteran, NRVTA-trained RV technician and NRVIA Certified RV Inspector.
Sheryl coordinates appointments, customer communication, parts and follow-up, helping keep each mobile service call organized from the first contact through completion.
Five fair questions to ask any mobile RV technician.
You can ask us these questions too.
1. What will I pay before repairs begin?
Ask about the service call, diagnostic labor, travel charges and hourly labor rate.
2. Will you diagnose before replacing parts?
Similar RV symptoms can have very different causes. Ask how the technician plans to confirm the failure.
3. What RV-specific training do you have?
Training doesn't replace experience, but it helps you understand the technician's background with RV systems.
4. Will you explain the findings first?
You should understand what was found and what you're authorizing before additional repair work begins.
5. What happens if it's outside your scope?
A mobile technician should be willing to say when a job requires a chassis shop, body shop, dealership or specialty facility.
Ask MilTech the same questions.
We'd rather have an informed customer who understands the service process before the appointment begins.

Mobile RV service FAQ
A few things customers commonly want to know before scheduling mobile RV service.
Do you come to campgrounds and RV parks?
Yes. We provide mobile service at approved campgrounds, RV parks, resorts, residences, storage locations and other locations where mobile RV service is permitted. Customers are responsible for confirming any campground or property restrictions.
What types of RVs do you work on?
We service many travel trailers, fifth wheels, Class A, Class B and Class C motorhomes, toy haulers and other RVs. The specific system, installation and accessibility determine whether a repair can be completed as a mobile service.
What does the $75 service call cover?
The service-call fee covers the standard mobile dispatch to locations within the normal service area. Diagnostic labor, repair labor, parts, materials and applicable extended travel are separate.
What does a diagnostic visit start at?
A standard diagnostic visit starts with the $75 service call plus the first diagnostic hour at $150, for a $225 starting diagnostic visit. Parts, materials, additional labor and applicable extended travel are additional. Specialized services and inspections may use separate pricing.
Why do I need diagnostic time if I already know what's wrong?
A symptom or fault code does not always identify the failed component. When the cause has not been confirmed, testing helps determine what the system is actually doing before parts are recommended or replaced.
Can you give me an exact repair price before seeing the RV?
When the scope of work and required parts are known, we can often prepare an estimate. When the cause is unknown, an exact repair total may not be possible until diagnostic testing is completed.
Do you diagnose 12-volt and 120-volt electrical problems?
Yes. We diagnose common battery, converter, inverter, charging, shore-power, breaker, fuse, outlet and related RV electrical concerns.
Do you work on RV slides and leveling systems?
Yes. We service many common electric and hydraulic slide-out and leveling systems. The specific system and failure determine what can be diagnosed or repaired in the field.
Do you service RV air conditioners and furnaces?
Yes. We diagnose many common RV A/C and furnace problems, including power, controls, thermostats, capacitors, motors, airflow and accessible furnace components. Some sealed-system or specialty repairs may require replacement or another service provider.
Do you perform RV inspections?
Yes. MilTech RV provides independent pre-purchase RV inspections with digital reporting, photographs and documented findings. Inspection scope depends on the package selected.
Can I supply my own part?
Customer-supplied parts may be installed for appropriate repairs. MilTech RV does not warranty a component purchased or supplied by the customer, and additional diagnostic or installation labor may still be required.
What should I send before my service call?
Send the RV year, make and model, service location, a clear description of the concern, and photos when possible. Equipment labels, model and serial numbers, error codes and short videos can also help us prepare.
Do I need power, water or propane available for testing?
It depends on the concern. Some diagnostics require access to shore power, batteries, water or LP systems. We will tell you what access is needed when the appointment is scheduled whenever possible.
What if the repair is outside MilTech RV's mobile scope?
We'll explain what we found and, when appropriate, recommend the type of facility or specialist better suited to the work. Major structural repairs, collision work, drivetrain repair and jobs requiring heavy shop equipment are examples of work that may need another provider.
Do you guarantee that preventive maintenance will stop future failures?
No. Preventive maintenance can identify visible deterioration, abnormal operation and maintenance needs, but no inspection or service can guarantee that an RV component will not fail later.
Not sure what service to choose?
That's okay. Tell us what the RV is doing, where you're located, and the year, make and model. Photos and fault codes help. We'll use that information to determine the best starting point.
