Nothing wrong with keeping a vehicle that you like. In Minnesota a 2002 F-250 would most likely be in a scrap yard due to rust. Not a lot of 2002 vehicles still on the road here. My parents kept a 2000 Caravan running until 2015, but it was really unsafe to drive due to rust before then.
Your original post implied that Ford no longer makes a F-250 with Super Cab and long bed. I had a 2005 F-350 crew cab with long bed and that was one long pickup! In fact, I got a VW Golf diesel as a daily drive because the F-350 was terrible as a daily driver.
