I think that one of the big drivers for keeping this engine small is the class C motorhome market that is based heavily on the V10. The 3 valve version of the V10 won't fit in the van front end and even the 2 valve can be difficult to service. On my 15 passenger van version the first step in changing the spark plugs is to lift the body off of the frame to get room to work. I would guess that on a motorhome that could be even more challenging.

Yep. The mod motors, even the single cam ones, are sooo wide.

I've never seen a 6.8 in a van chassis but I imagine it is tight.
