Central Truck & Diesel is a heavy-duty truck repair shop based at 1850 East F Street in Casper, Wyoming. It also takes RVs. You can bring the RV to the shop, or its team will come to you, which it describes as "expert repairs and services directly to you."

It says it specializes in "heavy-duty, medium-duty, and light-duty trucks, as well as heavy equipment, RVs, trailers, and buses." Its repair list includes brakes, engines, electrical diagnostics, HVAC system repair and transmissions, but it does not name RV types, brands or RV-specific parts such as slide-outs or awnings, so ask whether it has worked on your model. Its roadside assistance covers RVs within a 60-mile radius of Casper, and it names Glenrock, Douglas, Bar Nunn, Homa Hills, Antelope Hills, Meadow Acres and Midwest. It names no campgrounds or RV parks, so ask whether it will come to your campsite or storage lot.

It publishes no trip fee, hourly rate or diagnostic fee, so ask about the trip fee first when you call at 307-235-6685. Its listed hours are Monday through Friday, 7:00 AM to 5:00 PM, and it states no after-hours or emergency service.

It is a Cummins Engines & Allison Transmissions Certified & Authorized Warranty Dealer. That matters if your motorhome runs a Cummins engine or an Allison transmission, because warranty repairs on those parts usually go through an authorized dealer. It has been operating since 1987. It states no licensing or insurance and names no technicians, so ask who will work on your rig.

Google rates it 3.8 stars from 57 reviews and lists it as an RV repair shop. This is a good fit for an owner near Casper with a motorhome that runs Cummins or Allison parts, or a traveler within 60 miles who needs roadside help on an RV and can wait for weekday hours.
