    I'll be buying a Used (2002 - 2004) 36 - 40 foot DP next spring. An RV Salesman told me to stay away from the ISB Cummins engines. He said that it's the same engine that they put in Pick-up trucks, and that it wouldn't "carry the load" of a big Class A Coach. He also said that the 300 Cummins engines are the USB pick-up engines. Is he telling me straight ? I see a lot of used coaches that have 300 Cummins engines. Should I steer clear of all of these ?

    I would go to this site and post your question. There is a whole section on Cummins engine. They will shoot straight with you. Also before buying a used unit, you should have an engine and transmission oil analysis preformed.

    Good luck and come back and let us know what you do.

    I feel the ISB is small, but the 300 ISC has a good amount of torque and the ISL has plenty in all HP's it's offered in. Now to quallify, if you use the ISB in a light 32-34 foot coach with either no toad or a very light one it may well suit you. But for me the ISC is the minimum.

    We have a 32 ft Winnebago with a 275 Cummins ISB, It seems to have enough power for all of our stuff plus it tows a Suzuki Vitara. It's just 275 hp but the torque is well over 600 ft lb.
