Diesel --- front engine -vs- rear engine

There are quite a few front engine large diesels starting to appear out there. I think most of them are technically Class C's, but they are just as big and just as expensive as the Class A DP's. The ones I have looked at usually have hanger decks in the back. The one I really wanted had a huge lift gate in the back. It was designed to load heavy stuff like Harley's. The hanger was big enough for two Harleys all safely tucked away inside. My wife vetoed the idea.
