I am with you on keeping it as long as you can. Have had two trucks that after I finished paying on I was fine with running as long as they would drive. Bluetooth adapter to get my phone on. Don't need touch screen or heated seats or backup cameras.
With both my wife semi-forced my hand as she kept upgrading horse trailer, the primary reason for me owning trucks, until now I have a huge beast with a gooseneck trailer that I personally only put about 200 miles a year on. I think when it's time for her car to be replaced I'll take over the family car assignment and let her be the big truck person.
No matter the conversation I will always find a way to recommend the Gentlemen Bastards series by Scott Lynch.
Take some Oceans 11 or Now You See Me con artist heist plot, stick it into a fantasy world somewhere in the triangle of LotR, Discworld, and Verona, and have the dialogue written by Tarantino. It's such an enjoyable romp. I like to imagine Matt Berry doing half the voices.
