I drove a 2001 for 17 years before I sold it and bought my 2018. I'm 6'3", and my new truck is simply a bigger truck...I have more headroom AND leg room. I can stretch my left leg out and can't touch the floorboard.
I love the door set up, much better than my old 2 door access cab.
I also love the USB port. I put all my music (over 3,000 songs) on a flash drive, plug it in and let it play.
Also, nearly 100 more HP than my 2001.
My only gripes were that with it being a 4X4, it didn't come with mud flaps. and I didn't like the small tires. They also didn't last long. I replaced them with 16s..
