Adding 3rd Row Seats?

Hey, I'm new to the forum, so apologies if I'm posting in the wrong place. My wife traded in her JK for a 2018 Tahoe about 4 months ago and it didn't have a 3rd row, but I'd like to add one. The dealer said it originally had a 3rd row, though I'm skeptical. The back pillars have slits in the plastic shrouds for seatbelts, but the carpet has no holes. It's an LS I believe (no seat heaters, PO added leather to the seats). I actually picked up manual folding 3rd row seats and belts and actuators. Before I rip up the carpet, am I on a fools errand? Did they build the brackets into all the bodies at the factory, or would this require welding?

I could not find a single YouTube video of someone adding them to this model series, only the older ones. So if no one has ever done it on YouTube, can it be done??

thanks,
-Slim

I cannot imagine that GM would manufacture 2 different floor pans. It is easy enough to take off the rear (cargo) scuff plate and peek under the existing carpet; my money is on the floor having the anchors you need. Hopefully you picked up the mounting hardware with the seat.
Note.. you will lose about 5"-6" of cargo height/clearance once the seat is installed.

2009 was the year that the 3rd row became standard equipment, I believe. So unless its a PPV/SSV, it will have the anchors.

EDIT: I would have to think they just rolled the seat belts up, and put them behind the D-Pillar. If I am not mistaken, the seat belts, in all positions, are part of the SRS system, and if the belts were removed, you would have a SRS light on the dash since it cant detect the seatbelt pre-tensioners in those 3rd row seats.

Edit2: This has actually been one of my biggest complaints about GM on this series of trucks for years. I dont want third row, but they force me to buy them if I want this truck.

My 2012 is a PPV... it did not have 3rd row, but I was able to add it... the anchor points for the mounts were in the floor pan... just needed the brackets and hardware...

I too added a third row to my GMT900, I have never seen the floor to a K2 suburban but would imagine GM kept the same philosophy of standard floor pans.

Everybody has different needs, but I would like to at least mention a couple things about the 3rd row seating: I can't imagine an adult being able to comfortably sit there as their knees would be under their chin because the seat is only a few inches above the floor AND having the 3rd row installed will leave you with VERY little actual cargo area between the back of the seat and the hatch.
