The moral of that story (though stated for "entertainment use only") is to consider trading it in for something else at around 150 - 175K miles. This engine sounds like it would be fun to drive, but still more of a longshot for me due to availability of diesel fuel in a convienient spot at a price that would make it worth it. Additionally, I'm not going to put a lot of miles on what I end up buying. So I would have the advantage of many others reaching higher mileage before I would. So I'd be able to see how likely issues like this would be.
I still probably have around a year before I'm ready to buy something. Strongest contenders so far (though haven't test driven any of them), in order of likelyhood:
1. RAM 1500 with the Hemi 5.7
2. F150 with 3.5EB
3. Tundra with the V6 Turbo
Still interested, but less likely:
4. F150 with 2.7 (or even the V8 5.0)
5. Chevy Duramax 3.0 diesel
6. Gladiator
Another issue to mention with the strongest contender, RAM 1500. This is the last year for the Hemi 5.7. The 2025 engine with be an I6 3.0 turbo which will have option of a 420HP or higher spec'd 540HP. I'd be getting the 420HP, but often think first year anything is a bad idea. So that will be something to reasearch. Possibly buy one of the 2024 that is left over.
Currently we have the opposite problem of Covid production. When we got the 2019 Expedition new in mid 2021, there was very limited inventory. Vehicles aren't selling right now. So if that doesn't change much, could be good as far as availabitly. Not so much regarding loans and the economy.
Also have to see how the used market is at that time. Could get something above with low miles and get an extended warranty.
