  Company Contact:   Lee James
  Work Done on:   Class A - Diesel
  Service Performed:   I had lost power on hills so stopped to fix the
problem. They found an intake manifold gasket leak so
disassembled the top of that manifold, removing fuel
lines etc.), and fixed it with a new gasket.
Everything else was OK. The work was done quickly and
efficiently and the cost was very reasonable.
Unfortunately the throttle hookup was a little complex
and when we left the power problem persisted. We
returned and they noticed when the throttle was
depressed it was not functioning correctly and not
giving the engine sufficient fuel. They apologized
for that oversight (I have had that throttle linkage
issue before so that is a problem) and adjusted the
linkage so that it worked correctly. No charge for
that. The main problem was that we had to take the
bed apart twice to solve the two issues. I would
recommend these folks.
  Evaluation of Service Performed:   Done well on the original problem and when a second
developed, they jumped on that as well
  Value of Service:   Very Good
  Quality of Service:   Very Good

site with electric unit was taken into shop the next day for diagnosis. Diagnosed the problem was lift pump and repairs completed expeditiously.
  Evaluation of Service Performed:   All personal was both knowledgeable and professional, they are a Coach Care facility we also took our dog into the lounge area while waiting. We will start
to use them for our motorhome work when in their area. They also knew how to work with insurance to get covered.

  Work Done on:   Class C
  Service Performed:   They replaced the rotor and stator in my Onan 2800 under warranty 6 1/2 years ago, involving considerable disassembly. When I took the Onan out recently to replace the fuel pump, I noticed a missing motor mount, obviously left out by their tech. I called them, spoke to the service manager, and the parts arrived the next day at my house, no charge!
  Evaluation of Service Performed:   It shouldn't have happened, of course. But to make good on an error that they made 6 1/2 years ago, that smoothly and easily, was amazing.

  Date of Service:   9/22/2011
  Work Done on:   Class A - Diesel
  Service Performed:   The technician at Freightliner in Gaffney, SC performing a two year maintenance check on my diesel pusher on 9/20/11 noted that oil was leaking from the front main bearing seal and the air compressor gasket. They recommended that the repair work be performed by Cummins Atlantic in Spartansburg, SC. I called Cummins on 9/20/11 to make an appointment for the work. They scheduled me for 9/22/11. They analyzed the problem and indicated that in addition to the two aforementioned leaks, a third leak was detected between the gear cover and engine. This leak was determined by using dye and a black light. They recommended that the gear cover be replaced rather than renewing the silicone seal. It is their policy to replace the cover since there is a known history of warping over time on the ISB 5.9 engine. I authorized the work, but as it turns out they did not have the cover and it would be a week or more before they could complete the work. Since we were on the road and had prior committments at home we decided to defer the work. In addition to the oil leaks, I asked them to perform a 60 K check on the engine and during this check they noted that the CAC was covered with oil and that the drive belt was in bad condition most probably due to oil contamination. We asked them to replace the belt. A new belt was ordered, but the technician indicated it was a 1/2" too long. A second belt was ordered and installed. During the trip home the new belt started slipping whenever the engine was brought to an idle. Contact with Cummins during the trip home indicated they the belt could be slipping because the batteries were discharged and causing the alternator to be under too much load. Subsequently the unit was taken to Cummins Mid South in Kenner, LA to have the oil leaks repaired (this will be subject of another post) and to inspect the drive belt. They determined that the belt was too long and replaced it with a shorter belt. The belt no longer slips.
  Evaluation of Service Performed:   1.Cummins Atlantic was able to work me in at short notice but could not affect the needed repairs in less than a week due to their reported backload of work. I appreciated the professionalism of the technician who analyzed the problems.
2. The wrong belt was installed and had to be replaced which probably cost an additional $200 considering parts and labor.
3. Overall the rating for my experience with Cummins Atlantic is good.

  Service Performed:   New Onan 7.5 diesel generator failure after 120 hours of use. Cummins Atlantic was closest service facility. Required diagnosis of problem and correction. Thermostat and sender unit replaced under warranty. Problem solved.
  Evaluation of Service Performed:   Excellent people and first class facility. Sam, service writer, Chris, service supervisor and a Hispanic gentleman (sorry, name lost) who performed the work were top notch. Could not have been more accommodating or courteous. Nice waiting lounge. 4 hours from check in to out the door. I give this my highest rating.

  Service Performed:   2007 Newmar Motorhome...had "STOP ENGINE" fault alarm.
Spoke to Sam Evans, Customer Service Writer, who advised would work on unit upon arrival at location. Upon arrival at Cummins Atlantic, Spartanburg, SC, met with Mr. Evans. Unit was taken into shop immediately for diagnosis. Diagnosed the problem as a hole in heater hose and repairs completed expeditiously.
  Evaluation of Service Performed:   Service Writer Evans was both knowledgeable and professional...Mr. Evans advised they are not currently a "Coach Care" facility but are going through the inspection process. Allowed us and our dog into the customer lounge area while waiting. Seems like a new facility and very clean. I was introduced to Service Adviser Chris McKnight who explained the process of diagnosis and subsequent repair. Both Evans and McKnight were excellent in their abilities and we found this facility to be an overall pleasant experience for the circumstances.

  Work Done on:   Class C
  Service Performed:   Two warranty repairs on a 2.8 gas Onan.

The first was a complete rotor & stator replacement at 8 hrs, and included carburator replacement due to botched 'repair' attempt by Todd's RV & Marine in Hendersonville, NC.

The second was adjustment of governor due to loosened set screw at 50 hrs.
  Evaluation of Service Performed:   Excellent. I got 'soonest' appointments, work was done quickly & well. Waiting area is clean and nice.

They're convenient to I-26, and do all Onan repairs and service, as well as Cummins diesels.
  Value of Service:   Very Good
  Quality of Service:   Excellent
