I'm an "upgrader" myself, having owned a '90 (2nd gen), '00 (3rd gen), '08 (4th gen, STILL have it!) and a '19 TRD OR Prem (5th gen).
Each generation was an improvement in comfort, capability and power (except my '08 runs circles around my '19 despite both having a CAI as the only performance mods. The Sprint Booster on the '19 helped but she's still a dog, comparatively).
My only exterior upgrades on my '19 are the Predator steps over the tube steps that were on it plus the addition of the roof rack rails.
Love my Yotas!
