There's a reason why we don't yet see high boost, small displacement gas engines in heavy-duty/high duty cycle applications.

Until we start seeing them en masse, large displacement gas and/or turbo diesels are where it's at for heavy duty/heavy duty cycle applications.

Until that time comes, it's a moot discussion.

We don't see small displacement car sized turbo diesels such as the 1.8L TDI or 5.9 CDT in heavy duty/high duty cycle applications either. But keeping it in perspective, a 14L TD is small displacement for a 70k lb OTR truck. Much like a 3.5L engine for a 15k lb GCW pickup and camper.
Imagine the size of engines OTR trucks would require if trucking companies had to please truckers' irrational fears of the forbidden downshift on every hill or God forbid, not towing in top gear. They too would start losing carrying capacity due to engine weight.
