2023 Ram Bighorn with 6.7L Diesel < 300 miles ~53K
Warranty mostly used up sitting on the lot
2024 Ford F250 XL w/ 6.7 0 miles full warranty ~56K
2025 Ford F250 XL w/ 6.7 0 miles full warranty ~60K
Well, for five trips per year over a six year period, your 56K would earn: "For example, if you invest $1,000, the calculation would be A = 1000(1 + 0.04/1)^(1*6), which equals approximately $1,265.33. This means you would earn about $265.33 in interest over 6 years."
So 6 times $256.33 or $14,858 - your minimum 'opportunity cost.' You might well do better (maybe earning 24K in six years) buying 56K worth of Home Depot in a DRIP with Etrade.
But, then, what do you drive to Mississippi and back to Ole Virginity?
Well, if you're carrying cargo on one leg and dead heading on the other you rent a one-way vehicle to suite the load on each leg. Some ridiculously fuel efficient tiny car to carry the driver(s) one way, and a suitably capacious Penske to haul the load and driver(s) in the other direction.
If, on the other hand, you're loaded in each direction, I would recommend booking two one way Penske's hoping to find trucks that had moved household furniture to Virginia for your trip south and booking one in Ole Miss that had just brought some family's furnishings down from the Ohio Valley or similar.
Since it's about a 12 hour run, you might need a two-day rental - but, if you're a couple hundred miles less . . . maybe you could pull it off in one day?
Your fuel costs will be about the same (less if you are only loaded on one leg, of course). But you won't have paid liability and collision and on and on for the 360 days the $56K pick was (in the weather?) gathering dust. You did not mention what it would cost to insure the 2024 250 - did you check? You did not indicate that you didn't have the purchase price on-hand in cash - were you planning on financing this truck?
If you finance the truck and do the calculations (including financing fees, and the required comprehensive , you may well discover the $56K truck will cost you way more than may moons of necessary rentals. There is no such thing as a Zero Interest Loans or free lunches. If you are convinced there are, forget the forgoing and best o'luck with the fancy PUT
