As with some others, I prefer the feeling of owning something outright if it's within budget. It's awesome that some folks can and will invest smarter with the money rather than pay the truck off up front. I'd just rather have no payments and the ability to feel the freedom of no monthly payments.
I definitely have been there and understand that feeling very well. Having paid off some very big ticket items. It's a pretty great feeling. And along with that, you get to save whatever interest rate you may have been paying on it.
But today with 1.9% rates on trucks and loans that can extend to 8 years it's a different story entirely. This of course is saying that you have some money saved to begin with and are not financing the entire cost of your shiny new 75K+ truck. If you are someone that can barely make the monthly payments as is, well, thats on you. bad choice.
Just saying, I'd advise against paying for anything in cash, or paying off early, something that can be had for a very low interest rate. Because why? sure it's a good feeling to pay things off. But it's an even better feeling to take some money you earned and watch it effortlessly turn into more money to pay for that toy.
But sometimes it takes experience to learn. I should have never paid off my raptor so quickly. Should have just rode out the loan and kept that money in fairly safe investments. That initial 30k could have paid for the rest.
