TFL tests a new gen 2 R1T Tri Motor on some rocky icy terrain (starts at 14 minutes).
They also test a Ford Ranger Raptor with front/rear lockers for comparison.
Here’s a brief video of the R1T getting assembled. Lots of video cuts but you can get a general sense of the build process. Ends at 9 minutes followed by the Ford Lightning and the Hummer EV at 14 minutes.
