No problem. BTW, the tahoe/yukon is basically the same just no cargo room behind the 3rd seat (that makes it about 3 feet shorter).
I have the bench in the third row (so it has 2 seats of LATCH, but 3 tether anchors), but usually have the pass seat folded for 3rd row entry - so still only 2 seats in the middle. (But with the bench you can get ANY 3 across, I have done 2 regents and a BLVD). Right now, I have a seatbelt passenger behind the driver, a boulevard or radian RF in the middle, and passenger side seat folded. The third row has only 1 tether anchor that can be used by EITHER the center or drivers side position. i currently have a Regent in that drivers side outboard and a Monterrey booster in the passenger side outboard. I have done 3 across in the back, but it is only in a pinch and cozy. Not sure yet how I am going to configure 5. I probably have to either get rid of the beloved regent or go back to all RF in the back row (I did that when I was babysitting my niece and nephew last year)
As for tether all the seats, I will tether anything that can be, LOL. Only FF harness seats can be tethered (I only have 1 right now). Right now you have 2, right? How close to changing to a booster is your #1 and how close to outgrowing RF is your #3? Will they all need tethers at the same time? and #4 is a long time form needing a tether, and most likely #1 and possibly #2 will be out of a harnessed seat by that time.
One of the major things i don't like about the LATCH in a suburban/Yukon/large Chevy SUV, is that they put the LATCH int eh outboard passenger and center seats of the middle row - the outboard passenger seat is the one that fold for access to the rear seat. SO you have to either have the kids climb over or not use that LATCH position. That really doesn't matter if you are getting the captains chairs, as they both have LATCH, but I just wanted you to know.
