Advise please. Isb 5.9l 275hp w/4 speed allison

I'm looking at 2000 MH with the above. I've seen pro and con on the engine but not anything on the power combined with a 4 speed Allison transmission. Any help here would be appreciated.

The 5.9 24 valve ISB is a very good engine. Being rated at 275 HP I am fairly sure that the transmission will be a MT642 which is a heavy duty transmission with lock up torque convertor. MT642 is better than the AT542 which is also a 4 speed but non lock up rated at 235 HP max.

Jerry and Patsy, I'm looking at a coach like yours, thanks for your input. Is the single AC adequate in hot weather? We'll be mostly in Texas for a couple of years. Thanks for your help.
