I forgot to add that if you do find a Chevy chassis they are great too. I drove school bus for several years in retirement and we had many of the smaller buses on Chevy chassis with the V8. They were in severe service with lots of idling, and stop and go driving, seldom getting up to highway speeds. They had plenty of power, even fully loaded. The district would keep them until they got over 150K and then they'd sell them. It was seldom that they had an issue mechanically with them up to that time.
You will be happy with either chassis if you have a choice. The Chevy cutaway cab does give you more room than the Ford but the Ford is plenty roomy for us.
