Myself and two of my family members own DP's of the same vintage. All holiday rambler endeavor's 38' in length. Mine and my brother's are both '99 models with the 275HP cummins ISB. My dad's is the C7 CAT with 330HP. I have driven all three. All three perform great. The CAT does have slightly more noticeable power but not a heap more.
I like my cummins ISB. It has 660 LB/FT of torque. The power is more than adequate and pulls hills with ease, even heavily loaded. All of ours have the allison 3000 series 6 speed. Great transmissions!
Mine gets a hand calculated 9.63 MPG. This is combined flat, in the hills, and quite a bit of generator usage. My dad's with the C7 gets about 7 max. So yes, he has more power, but he gets less mileage.
Would I rather have the CAT? Not sure. I do like my fuel mileage better than his, and mine gets me where I need to go with ease. Pick the cleanest rig you can find and don't worry about the engine.
