Are gas engines ever going to catch up?
Our creaky old Cummins powered truck (bought used) seats 4, does about 20-23mpg bobtail and 12mpg towing a 5th wheel trailer at 22,999lbs. It's mileage is somewhere in between hauling a camper and/or...

You don't see 18 wheelers with gas motors. That tells me all I need to know
Not comparable unless you're driving the same number of miles or running the same working hours.
Personally, I trust test done by these guys at The Fast Lane Truck (and Car) because they test on the same highway using the same tools, consistently. Unlike people on forums. Watch some of the real low diesel MPG numbers going up "the gauntlet" and how they tow vs gas motors. They all do fine, but clearly some are better than others.
