Meh, cost of doing business in my opinion. When towing, it doesn't matter anyways. I had a 99 24v dodge for a while. And while towing I would get 9-11 mpg's (sure empty it would get 18, but I didn't daily my trucks, so it made no difference to me). My 8.1 gets the exact same towing mileage as the 24v. And my old 96 K2500 with the 7.4 vortec got the exact same empty/towing mileage as my 8.1 truck does now. So factoring in the higher cost of diesel fuel (in most circumstances...I know in my area gas and diesel are the same cost right now, but that's not the normal, diesel is usually always higher) then factoring in the higher maintenance costs that diesels have...in my opinion it's a freaking wash in cost. But a gas BBC takes so much less maintenance. I just don't understand the fascination with mpg's in our society lately. When you start factoring in total costs of owning a vehicle, and older BBC truck saves you lots of money even getting 8-9 mpg's, while still giving you the ability to tow pretty heavily (as evident of the pics above in this thread).
The stupid gas vs diesel saga will probably go on forever. Those with diesels will do everything they can to prove that their choice is the better one, and guys with gas will do everything they can to prove that diesel isn't worth it and their BBC is fine. To me, it's all about a cost/benefit analysis. How much benefit will I get for the cost I have to shell out for it. And so far for me, diesel isn't worth it and I can get by just fine with a BBC, even with it getting single digit mpg's.
The one thing I do find interesting is how the manufacturer's are slowly making the move back to focusing on gas. In the 80's and 90's emissions on gas starting getting crazy, that's why you saw a big serge of diesels in the mid 90's into the late 2000's. Well now you are seeing crazy emissions being placed on diesels making it less cost effective to own one now, however the technology for gas has caught up to the emissions restrictions to the point where they can stay emissions legal but still put out great power and get pretty good mileage at the same time. That's why Ford came out with their new BBF, and there are talks of Chevy coming out with a new BBC, plus the introductions of the 6.2 and 6.6 gas motors. It'll probably be a pendulum swing every 15-20 years or so from the hot item being gas or diesel cause that's probably how long it takes the manufacturer's to figure out how to stay current on emissions while still producing a great product that's worth a crap. Interesting to think about at least
