My early childhood recollections, late 50's and 60's of these vehicles were 2 door, 3 door and early 4 doors "boxes" called Suburbans. Somehow as I got older I heard of "Tahoes" and pictured them as smaller vehicles. Now I acquired a 97 Tahoe and my original picture went out the door. So when did Tahoes come about and what is the major differences in them. This question came about because a couple of days ago saw a newer Tahoe that looked extremely large. Not looking for the down to the mynute details but overall in looks and wheel base and drivetrain.
