I would buy the diesel if it
I would buy the diesel if it matched or was closer to the max trailer tow ratings. It is odd that the ratings don't match. I agree with the other writer above, the manufacturers really miss important points like mpg while towing, oil consumption expectations, overall durability/life of the engine and resale value of the truck. A commercial diesel engine is very durable. How close can these automotive diesels compare? We know a long life is possible in a commercial diesel.
