just my opinion, means nothing ..
I prefer the manual shift. I’m not sure if it’s marketed as shift-on-the-fly but I have shifted it while moving (low speed) every time. Fwiw any floor shift 4x4 is easier to shift while the vehicle is at least rolling. The power wagon does have all those cool buttons so I can see the allure of the electronic shift. I believe i read it is becoming standard next year.
The wheels I have no preference either way. I love true beadlocks on rock crawlers that are using sub-10psi in the tires, they’re a necessity. But, I don’t think they’re necessary on the PW. I believe They say “beadlock capable” so I assume you can mount the tire with or without the beadlock but I cannot confirm that.
