Are you having issues now? Is it shifting funny or bad? Drop in gas mileage? Sounds like you like the truck. Personally if I needed a major repair or thought something was wrong I'd trade it in. Not the best timing with used vehicle prices at an all time high. Advantage of trading it in now is the "low" mileage. Under 100K miles dealerships and private buyers still can get financing or offer fairly easily. Many expect that buys may be had in 2024 because repo's and ability to qualify are increasing.
