My 1st gen crew cab Tundra carries adults in the back seats just fine. Access cab is a no go beyond kids and dogs.

Sure, a later gen crew cab Tundra has more back seat room, but I personally like the first gen. I sold my 2017 Tundra and bought another 2004, because of preferences...,,newer wasn’t ‘bad’ in any way, just thought the 1st gen was overall better, especially for the $.
