Cat 275 hp Diesel

I can't speak to the CAT 275HP engine never having had one. I currently have a CAT 3126E, 330HP, engine in my 36' RV. I pull a 4,000lb toad and the engine has been superb, no issues. I had a commercial fishing boat with two Cummins 903 non-turbo mechanical diesels, V-8's, that ran 24/7 from June to Sept and sold it with 4,500 hours on them. Never had a problem of any kind. Just changed the oil and changed the belts once in 4,500 hours. They too were superb engines! There are lots of diesel manufacturers out there and you can find dissenters for every one of them. But, if you service them as recommended by the manufacturer you will rarely experience serious problems. Unfortunately too many RV owners don't understand diesels and baby them or ignore the required maintenance and service they demand and too often cause the very problems they complain about! Drive the hell out of them like they were designed for and be happy!!
