Thanks again for the on topic responses I appreciate it and it is helping to get a reasonable expectation level.
I want to keep the cost below 100k and more preferred is below 80k on a used coach. From what I have seen with a 36 foot or shorter a diesel coach towing 9,000- 10,000 lbs will at a minimum need the Cummins ISC (1050 ft lbs) and preferably the ISL (1200+ ft lbs) to get the job done. On the CAT engine side, the 2006-2007 Fleetwood Expedition which I have been considering with 850 ft lbs of torque is an absolute minimum. As I see here with the comments I can expect slow downs in the mountains as I have previously had in my gas coach when I was towing the smaller trailer & less weight. It sounds like I'll be back to the familiar 35-40 mph range unless I can find that elusive ISL on a smaller coach in my price range. Do you think this is a reasonable compilation of information in this case???
Weight Police types, no further comments are requested. Thank you
