Diesel trucks are definitely expensive to maintain! It really depends on how often you tow and how much weight you're towing to justify the expense. It sounds like Toyota has bumped up the towing and payload capability on the Tundra so that your average person doesn't have to go with a heavy-duty diesel.Can’t wait to get back in a Tundra, got out of my 11’ in 2019 and bought an eco boost. That was a mistake and traded it in on a 6.7 Superduty and an even more expensive mistake. Should’ve never left Tundra but they were soooo dated. Glad they’ve made a few updates.
