OK, will this be a skirmish or an all out war?

Personal opinion says its just a matter of preference. I've had Cummins and now have a Cat. It's not fair to compare a 5.9 Cummins to the larger displacement Cat but since I'm not in a speed race anyway, I have found both to be good engines. It's a take your pick.

Johnson, this is like asking Ford vs. Chevy or vanilla vs. chocolate. I have had both and really could not give you scientific data favoring either.

However, we are with our second Cummins and that is our preference based soley on service. Cummins is generally close to the interstate in all major cities. Cat on the other hand more times than not is tucked away in some industrial park that I have zero knowledge of their where abouts. Why you say---look at their respective markets. Cummins is serving the over the road trucker and wants to be accesible to the interstate. Cat is serving the bull dozer and off road equipment market which is primarily local and does not need to be imediately accesible to the interstate.

Cummins seem to be cognizant that this is my home away from home and at Cat you need to walk through the mud associated with the bull dozer mentality. Cummins most generally has a waiting room where Cat serving a drop off market is not always aware of you as a customer and your personal needs.

I have gotten to really like the Coach Care service offered by Cummins and I am not sure that Cat has a similar service. To see what this is about check out Cummins .com or possibly Coach Care. com.

Good luck however you elect to proceed, Ken,'04 DSDP....

I bought the coach & floorplan I wanted and then checked to see what engine is in it. At this point, I think I would be more picky about the chassis mfg than I would about the engine being CAT or Cummins. I would choose a Spartan Chassis over a Freightliner if I had a choice in the coach & floorplan I ...and the spouse, of course ...wanted. As Ken mentioned, the Cummins Coach Care facilities are nice to work with, but I've never had a CAT so don't know what you would find with their service centers. I believe either engine would serve you well.

Well, both Cat and Cummins make a good engine. I take issue with the description of Cat service and locations though. I've never been anywhere in the lower 48 that I could not get Cat service. Also, they do not cater to construction equipment only, look at the 18 wheelers going by sometime. Every shop I've been in had an equally nice shop for heavy equipment and another area for RV's and 18 wheelers. The last one was in Des Moines and was a beautiful shop if you wanted to hang out. Same out in Oregon.
By the way, a Cat dealer told me the reason they have fewer shops than Cummins was because the Cat's don't break as much....lol no flames, it's a smile on my face!

Back many years ago, the Cummins was thought of as a stationary diesel engine for use on the likes of a base-mounted engine driving a pump, generator or the likes. Cat was though of as an OTR or transporation engine. Over the years, Cummins started offering more "medium-duty" engines for the transportion industry.

The little 5.9L Cummins used in the Dodge trucks started it's life as an irrigation pump driver and has evolved into a great "medium-duty" engine. I use the term "medium-duty" because it is not in the same arena as the "light-duty" Ford Power Stroke or the GM Duramax, but it is not in the same league as the heavy duty diesels.

Both are equally good engines. The one thing that makes them both trouble-free is proper maintenance. If you don't maintain the engine, neither one will be worth a nickle.

We are on our second motorhome, both Kitty powered with no complaints or problems.

Have friends that have Cummins with no problems.

Both CAT and Cummins are good engines as long as maintained.

I don't know anything about that one ...most likely a proprietary build unique to their coach line.

Regarding The Velvet Ride Chasis by Magnum, Safari/Beaver owned Magnum and were one of the few using thier own chasis under thier motorhomes. Velvet Ride was used in Safari's higher end units and was a very solid, heavy duty, nearly no maintenance chasis.

Both are grest engines, however you stated 300 HP, they are different in engine size and displacement as follows.

Cummins ISB 5.9 l. 300 HP
Cummins ISB 6.7 l. 300/330 HP (new for '07)
Cat C-7 7.2 l. 300/350 HP
Cummins ISC 8.3 l. 300/330/350

Torque rating also vary with least to most as you go down the list.
