Gray Diesel & Equipment Services is a truck and diesel repair shop that also works on RVs, with locations in Lincoln, Nebraska and Lexington, South Carolina. You bring the RV to one of its two facilities rather than having a tech come to you.
On the RV side, it works on mechanical repairs, diesel engine repairs, brake repairs, suspension repairs and exterior repairs. This is a shop built around heavy diesel equipment, trucks and trailers, so an RV with a diesel engine or chassis issue, a brake or suspension problem, or exterior damage fits what it does day to day.
No trip fee, hourly rate or diagnostic charge for RV work is published, and no hours are listed. Ask about all of this when you call, along with whether a warranty applies to the specific repair. It describes itself this way: "Gray Diesel & Equipment Service provides complete RV repair services."
Google rates it 5 stars from 18 reviews.
This is a good fit for an owner near Lincoln or Lexington who needs mechanical, brake, suspension or exterior work done and would rather bring the rig to a shop that already handles heavy trucks and trailers, not a traveler looking for a mobile tech to come to a campsite or a driveway call for appliance or system repairs like AC, fridge or slide-outs.
