Caterpillar Diesel

Suggest you check parts costs and service availability. We have Cats in two boats and have found parts are more expensive, one source for us in the Pensacola Fl. area, and knowledgeable mechanics limited. Many more Cummins engines in use than Cats around here. For that reason when we shopped for a DP we ruled out Cats.

Kind of "Ford vs Chevy" question.

There has not been a bad diesel engine in the last 15+ years.

Buy the coach you like. The likelihood of engine problems on any of them is quite small (assuming it has been maintained).

Mine has a Cat and I've done nothing to it other than regular service. Never had a single problem.

330 CAT here, purrs like a kitten. 42k miles.

Yes Caterpillar is back with road trucks with Caterpillar CT660 engines. Most powerful diesels produced yet. Have several operating out of Garden Grove, California.

CT660 might be a little too powerful for a motorhome.

They started making their own equipment for on highway usage again. My understanding is the engines will be available soon for chassis manufacturers once again. LINKY to CAT trucks

Thanks for all the info. I've driven a cummins diesel all my adult life in a pickup. Used cat diesels in other applications and loved them both. I know cummins can have problems as well. The issues I heard about were the ones in mid-2000 and now Cat is out of the over the road business.

I see several MH for sale with around 20k and wondered where the good stories were. You normally only of the bad ones I know, just wanted to hear the good ones!

Thanks again for the input.

I have the 3126-E Cat engine and it has been a good engine through 50K miles. Had two Cummins engines before that and blew a hole on both through the block. But that was the 5.9 Cummins engines.

I ran one 425,000 miles. 1 injector, under warranty, filters and oil changes. Seemed to like to be run hard, 65 and over. They can be expensive to fix/overhaul but seem like good engines with thousands running in boats.

I'm retired from the trucking industry and I was behind the wheel of CAT engines most of my 44 years. 1.2 million miles was the furthest I drove one engine before a rebuilt. And 750,000 was the least amount of miles before a rebuild. This past spring I had my Workhorse in Joe's RV Lake Havasu City, AZ. (Workhorse dealer in L.H.C.) and one of the mechanics was working on a DP with a CAT engine. I quipped nice engine and he replied back to me, all the CAT's are nice except the 330 H.P. I didn't ask any other questions as I was leaving but he told me they work on a lot of 330 H.P. CAT's in that shop.
