Once again this topic is as old as the hills and so are many of the offerings here.
We tow with an 8.1/Allison combo and it does just great. We don't need to scream the engine and the Allison keeps the engine in its sweat spot most all the time. Trailer grosses at 12.3k and if I watch the big pedal I can average over 9 mpg on a tank. By anyone's book that isn't very good but nothing towing that weight does substantially better. Diesel in our area also remains at between .40 and .50 cents more per gallon than gas so recouping the added expense of a diesel equipped rig takes a lot of miles. Many people simply don't keep their trucks long enough to make that issue much of an issue at all or long enough to gather the 3-400,000 miles they think they'll put on their diesels. Take a look anywhere on this forum. You'll not see too many rigs with hundreds of thousands of miles on them towing their big new trailers. Reality speaks otherwise. In fact, there is demand in Class A rigs for more luxurious gas rigs. Why? It's because the diesel rigs and their chassis are significantly more expensive than a gas counterpart and many people realize they simply won't see the rig rack up big miles. So they are looking for something that fits into their budgets better and still get the job done. Have you ever seen the difference in over the road performance between today's gas and diesel Class A's?
If you also want to compare gas and diesel and their merits please compare current offerings and not compare your bright shiny new diesel to your old gas 150/1500 and declare that the diesel wins hands down. Just what kind of comparison is that? Funny how you read that here over and over again.
