Regardless of how much towing you will actually be doing or what you will be using the truck for. Put 5,000 lbs behind a gasser and you dropped to 8 mpg, put that same load behind the diesel and you still may get 10-14mpg.
Ever consider that he may want a crew cab truck AND a long bed? Can you get that in a half ton?
Maybe he doesn't need the diesel for towing, but perhaps needs the bed space and doesn't want a gasser and 10 mpg in a 3/4 ton truck?
Perhaps he plans to keep the truck for 500,000 miles, or perhaps he is curious as to what kind of mileage the truck will get and wanted to see what people were getting out of them and was asking a legitimate question in regards to what the total cost of ownership would be?
Would you buy a car with out knowing what it will cost you to insure?
Why is knowing how much fuel it would use any different?
Knowing the approximate fuel mileage of the vehicle you plan on purchasing is a consideration of the total cost of ownership.
Call me a cheap ass, but when I car shop....
I look at the potential repair costs for fairly common parts, shocks, struts, starters, alternators, etc.
I look at the potential repair costs of catostrophic repairs (trans, engine, axles)
I look at the insurance costs.
I look at the cost of fuel.
I look at the replacement cost for wear items (brakes, tires, etc)
I see nothing wrong with the question.
Not to mention if you are going to spend 50k on a new truck that gets 12 mpg and have the option of considering very new used trucks that may get 18mpg and only cost 30k.....being informed is not a bad thing, nor is it a declaration of what someone can, could, should, afford to drive.
You read way too much into what i said. I was rephrasing what i thought shaffer was saying. I was in no way implying it was a dumb question. But based on your replies a Duramax is more expensive in almost every category except the gas mileage towing.
You do make good points regarding what the OP's dad may want out of a truck, we do not fully know, i just went off of the Op saying he would be pulling a trailer here and there. I do agree with you 100% also on all of the things you look at before buying, nothing wrong with being an informed buyer.
Fwiw my 1/2 ton gets 12 MPG pulling my Fullsize blazer from Traverse City to Copemish. It is a mix of 45 and 55 mph driving with quite a few stops for turns or at lights.
