Very happy with the 3126 in the Sahara. CAT stopped making OTR engines after the DPF era because their C13 engine (2007-2009) were fraught with problems. So after 2010, you really don't have a choice; it's Cummins or Ford V10 gas.
A 3126B with an Allison 3000 tranny is as bullet-proof a drive train as you can get. Mine is going strong at 150,000 miles. They are limited to about 350 hp, but that should be plenty in the length range you're looking at.
A couple of things to look for in the Mx logs when looking at a coach with a CAT motor are valve lash adjustment done at 30,000 and every 100,000 after and the fan hub bearing which has a grease fitting on some motors. It's easily forgotten during chassis service.
