Their pics have a winch I'm noticing... The new mirrors look the same. Looks like the body will still be gen 4. I'm wondering if the next "totally new" iteration will have the HO Hurricane in the gasser version. I know they are saying no, but... I've heard that before also. It's interesting to note how they are "structuring" their "refreshes." I think we can be pretty sure a new tranny on the Diesel. The 2019 changes were primarily everywhere you cannot see...but does make a difference particularly with the 6.4 transmission enhancing its functionality substantively. This could be another "incremental but market attractive change for certain individuals particularly if they put a diesel in it. Ups the game quite a bit over the present "off road" package but not at the level of a power wagon AND keeping the Payload up in the real 2500 range vs a Power Wagon.
And then, maybe in 2025 we get a big reveal with the new body, new engine, built on the other 2019 changes underneath tweaked with experience... I still don't like the Rebel front end though and would prefer one of the other fronts like the night version maybe.
