This is end of model year, so discounts should be available on gasoline trucks but diesel, probably not much.
Another alternative to consider, especially if you just need a truck to pull your trailer to local shows, or you don't need to use the truck for your primary transportation, is to get a rebuilt truck with a salvage title. I'd not recommend buying one of those from just anyone, but there are people like one local used vehicle lot and also my nephew who do buy very nice salvage title vehicles and fix them and resell. My nephew drag races and tows a huge trailer, and all he's used for the past 5 years are salvage diesel duallys that he bought and repaired. My sister and her husband have been driving salvage SUVs for about 7 years now. He buys them down South where they don't have rust. He rebuilds engines himself. He farms complicated bodywork and paint out to a friend with a body shop. If there's no frame damage and no corrosion, the rest of the truck can be rebuilt or replaced for years. The local car lot man here does essentially the same. He buys vehicles at auction, or buys salvage vehicles, and repairs. If people want something in particular, he will look for one at auction.
"Old" vehicles have low book values. They have low tax rates in the states that charge property tax on vehicles. If you can pay cash, you own the vehicle and have no payments and no need for financing. A "salvage" vehicle can be salvaged for many reasons, and not all of them have extensive damage. You can upgrade the thing using used parts. like leather seats or stereo systems if you must have those things. The downside is you either need to have a cheap mechanic lined up to do repairs if the need arises, or you need to have the cash on hand to replace whatever needs replaced. But if I only needed a short-haul weekend truck, I'd definitely consider something decent that has a salvage title. I own more than 1 vehicle, so I always have something else to drive.
