Over the years I’ve had the pleasure of having 2 different RVs with that combination. A 1997 Monaco Signature and a2002 Monaco executive. The 1997 had a bit over 200,000 miles without any i issues whatsoever with engine or trans. The 2002 has currently 70,000 miles, with out a single issue. The Ecec was bought with very low mileage Before purchasing we had a Cummins tech hook up a computer to the engine and he was able to verify engine hrs, and how many of the hours were idling and a lot of other info on the engine. Bottom line he said the engine was like new. You’ll love the power, and the 2 stage compression brake. I’ve had 5 different diesel pushers and that combination for a power unit has been the best.
