One of the most common questions we get at MilTech RV Mobile Repair & Inspection is:
“Do you work on everything an RV might need?”
The honest answer — and the one RV owners appreciate most — is no.
Not because we don’t want to help, but because some repairs simply aren’t safe, legal, or realistic to perform outside of a full-service shop.
As a certified RVTAA / NRVIA mobile technician, here’s a clear breakdown of the repairs we do not take on, and the educational reasons behind each one.
🔧 1. Engine & Chassis Repairs
This includes:
-
Engine diagnostics
-
Transmission issues
-
Brake systems
-
Steering & suspension
-
Axles & major drivetrain work
These systems require heavy lifts, shop tools, and automotive certifications. Mobile environments cannot safely support this level of mechanical work.
⚡ 2. Internal Generator Repairs (Beyond Basic Maintenance)
What we can do: oil changes, filters, spark plugs, basic troubleshooting.
What we won’t do:
-
Carburetor tear-downs
-
Stator/rotor replacement
-
Internal electrical repairs
Onan and other generator manufacturers require these repairs be done in certified shop environments due to liability and workspace requirements.
🏚️ 3. Full Roof Replacements & Structural Rebuilds
Mobile techs can seal, inspect, and patch — but full roof membranes and structural repairs involve hours of labor, insurance processes, and large indoor workspaces.
A full roof job is simply not a mobile-safe repair.
❄️ 4. AC Compressor or Sealed-System Repairs
RV AC units aren’t like home systems — replacement is the industry standard.
If the compressor fails or the sealed system leaks, the unit must be replaced, not repaired.
↔️ 5. Major Slide-Out Rebuilds
Slide adjustments? Yes.
Slide alignments? Yes.
Complete mechanical rebuilds? No.
Big repairs like Schwintek rail replacement, slide floor rebuilds, or through-wall work require cabinetry removal, jacks, supporting structures, and hours of disassembly that aren’t practical mobile.
🛠️ 6. Fiberglass & Body Damage Repairs
Fiberglass cracking, delamination, and collision damage belong to RV body shops with specialized resins, tools, and climate-controlled curing environments.
🚽 7. Black Tank Replacements
We can clear clogs, replace gate valves, and diagnose tank odors.
But full tank replacement requires removing underbellies, frame supports, and sometimes slide rooms. Not mobile-safe.
🟧 Why This Matters: The Educational Takeaway
A great mobile RV tech isn’t someone who “works on everything.” It’s someone who knows:
✔ what can be done safely,
✔ what must go to a shop, and
✔ how to guide you to the right solution without wasting your time or money.
Being transparent protects you, your RV, and your warranty.
🟩 So What DOES MilTech RV Do?
Here’s where mobile service shines:
✔ Electrical troubleshooting

✔ RV refrigerators
✔ AC service & parts replacement
✔ Slide-out adjustments

✔ Winterizing & de-winterizing

If it can be done right, safely, and professionally in your driveway or campsite, we bring the fix to you.
