Well, I may catch heat for this but...the most underwhelming and quite frankly, disappointing "refreshes" I could have expected.
Exterior: At least they didn't completely destroy the looks. The Rebel now is just mild, at best. It used to be that when you saw a Rebel it screamed "wow, that's bold." Now? It looks like a half-Tundra, half-5th gen Ram. I'm sure it will look a little better with running boards and some of the other additional trim they put on. It will never be a true 5th gen Rebel though. The 4th gen to 5th gen Rebel was a homerun, if not a grand slam. The 4th gen Rebel's were aggressive as is. The 5th gens just made you go "woah." 6th gen is basically "Oh it's a standard limited/big horn/laramie with a black grill and sport hood."
Interior: Maybe the only bright spot? Passenger side dash looks cool with the screen but its me, only, in my truck 95% of the time. Big screen looks slightly reconfigured in terms of layout/display. Other than that? Meh.
Drivetrain: Mega, mega facepalm. The lack of a V8, even a mild/more-efficient one, is a huge blow. Turbo'd V6...good luck to anyone hoping to get 100k or more out of that motor without dropping some serious repair costs. Anyone getting one of these trucks: Get a 36k 3 year lease and give it the hell back if it doesn't start giving you problems. Even with the 5th gens, the 5.7 was still the 5.7. Yeah they have the longstanding lifter issues, the etorque caused some issues, but I'd rather take my chances with that than start scorching pistons, breaking internals, or having turbo's cook themselves.
I will probably keep my 2019 till it dies and pray they either a) Start putting V8's back in the 1500's, if not then b) go to another brand that still puts V8's in 1500 or c) move up to a 2500 which you have to imagine will still have a V8.
