If you plan on keeping it after the warranty expires, you better plan on a few thousand for repairs. Or maybe closer to 10k. Nothing is cheap to fix on the diesels. After owning one for a while, I am REALLY tempted to go back to gas for that reason. The MPG difference is not huge unless you drive a LOT, like every day towing. I'd venture to guess that 80% of diesel pickup truck owners buy the oil burners for the purpose of "little man syndrome". And I were one of them, and wished I'd stuck with a gas burner. Think about it. 16 quarts of oil for the diesel. 6 or 7 for the gasser (half as much basically). You save money right there. Diesel fuel costs more. You have to get better MPG just to pay for the price difference in fuel. If warranty's up, then you have to figure in repairs....you replace an injector on a gasser, a couple hundred bucks worst case. One injector in a durmax, figure closer to $1,000. Then removal and cleaning of the DPF once every so often. Gassers don't have DPF's. DEF tanks, and the problems (or potential problems) with DEF and that system. If you're a business and can write off the repair costs, it might be worthwhile but for an individual, I just can't see it paying off unless you just have the money laying around with nothing better to waste it on.
