Are there 2 different Monaco's?

For those of you who had the CAT C9 and had a bad experience, my heart goes out to you. However, we had a 2005 Revolution LE with the CAT C9 engine in it, and it was a fine engine. I really couldn't see any difference in dependability or reliability between that and the 4 Cummins engines I have had. We put 90,000 miles on the Revolution with next to no problems.

Your C9 is an early C9, not saddled with the emissions like those of 07? and later Cats. Those are the ones to stay away from. That ACERT emissions system really changed everything.

Think about this, CAT did not get out of the on highway market after the 07 to 09 engines came out because they were ultra reliable sought after engines and they were making tons of profit on them. More like the engines were giant turds with the ACERT system and they were losing money on warranty service . My CAT C9 cost about 30,000 in 2009. In 4.5 years, Cat paid out $40000 in warranty work.

Keep in mind this was in an RV that was always religiously maintained according to specs and had an easy life driving down the interstate. Think about the trucker that does 60,000 miles a year in the oilfield or farmfield or quarry or the engine on a shrimp boat or a marine generator that is not as well maintained and does tons more miles and hours than a simple RV will do. How much did CAT pay out in warranty for these guys.

From experience, the issues are never fixed, they will just fix it until the same part breaks again.
