Based on over 100k miles driving 4 coaches, Go with bigger every time. My first DP was an ISC 8.3L because I knew the ISB at any HP rating did not have enough torque. I now have a ISM 10.8L Love it.
Although I wouldn't mind getting the big ISX 15L. The smaller engines will probably do the job, but the west is vast and tall and you have to worry the whole way. Good Luck.

So Cummins, Frieghtliner, Fleetwood must be repairing those little ISB's left & right as they've been put into many different MH platforms for some time. I doubt it's been a issue for anyone who has one, anymore than a larger ISC or any engine. Design limits and caution just thrown into the wind by the engineers ??

All those gassers & little ISB's must be terrified heading to the vast and tall great out West. In reality since you've really never driven a ISB, you don't have any experience with it.
I guess I should have added the words. For me. Someone in there. I never said they wouldn't do the job and I certainly never said they break in any way. They just aren't enough for me. After crossing the Rockies more times than I can remember. I want a lot of power. I don't like maxing anything out. I feel things last longer if I don't run them at full power all the time. I have driven 3 coaches with isb. Dads, brothers, and brother in laws. All 3 of them agreed with me and all traded coaches after a few years. Buy what you want and enjoy your day
ISB didn't have enough torque for what? I would suspect that is your personal opinion, as they go up and down and straight and flat just like any other MH. Unless of course you have some data to support your statement.
