Probably bed size.

Bed size on contemporary F150s is also a joke. They're mostly just suburban mini-vans for the macho set.

The Rivan's bed size is similar to the Maverick.

Bed lengths for reference... 54" Rivian R1T 54" Ford Maverick 64" Honda Ridgeline 66" F150 Lightning

I own a Ridgeline. The bed is fine for chucking some camping gear, but it's nowhere near long enough for lumber, sheetrock, etc. Mountain bikes don't fit upright, even with the front wheel off.

The Rivian is 17" longer overall than a Maverick and 7" longer than the Honda. It's bed is really small - fine for casual use, but hardly suitable for "working truck stuff". And that's not the market Rivian is targeting, so that's fine.
