I guess I made that statement partially looking directly at the Cybertruck's actual performance and partially looking at the Cybertruck relative to other offroading vehicles.

The reality of the situation for the Cybertruck is that it's a pretty heavy vehicle (with as you mention) not great stock tires -- but everyone knows that. The absolute biggest issue with it though is that the tie rods for all 4 wheels don't seem to be adequate -- especially if you're coming down pretty hard on a single corner. There are countless videos out there where you see Cybertrucks with floppy wheels -- especially out offroading.

Secondly, the Cybertruck has sub-par departure angles where the hitch just gets dragged along the ground. Combined with the realization that the hitch is only rated for 160lbs of vertical load (and it's structurally attached to the frame with aluminum -- which cracks, not bends). I'm not sure if I'd be comfortable doing much beyond just bumpy roads with the truck.

Finally, the breakover angle is just not good at all either. Ground clearance doesn't mean much when the wheelbase is so long. The Rivian sits at about 15 inches of clearance with stock wheels and the Cybertruck comes in about 5% shorter at 14.4 inches. Not only that, but the Cybertruck also has a 5% longer wheelbase than the Rivian and its suspension does not articulate as much -- especially at full lift.

Real world, this means that the Rivian's departure angle in the truck is 30 degrees (plus a little more). The Cybertruck sits at 24.7 degrees in its drivable mode (it goes up to ~27 degrees if you have it in the crawl "extract" mode). There's also a 3.5ish difference in breakover angle as well.

Relative to other "standard" offroading 4x4s like the Rubicon/Wrangler or Land Cruisers, the Rivian is at best average and the Cybertruck is decidedly worse. Couple that with the R1T being able to independently power each wheel, the Cybertruck is IMO more recreational than proper off-road.

I'm not here to gatekeep so I will point out the obvious and say that the Cybertruck is for sure, a better offroading vehicle compared to most recreational/luxury vehicles out there. I'm just not sure that I'd qualify it as anything better than "okay?".
