I love my Tundra but it's getting up there in miles. It has 91,000+ miles which I know isn't a lot for a Toyota but I'm thinking about retirement in a few years and I don't want to go into retirement with a truck with 200,000 miles on it. I've had great luck with Chevys in the past, may favorite was my '98 Z71 1500 with the half doors in the back. Double cab? I don't' remember. I'm eyeing a 2020 of the same configuration. Anyone own one that has owned an earlier one like I had? Do they compare, and what are the pros and cons of them. I loved that Vortec V8! The one thing I really miss having is that G80 locking differential. Tundra is crap with their electronic diff. (fancy antilock brake foolery)! Thoughts?
