Thanks! I took them to a Tech yesterday and I think we were out there for an hour trying to get the Nautilus' to fit 3rd row, but they wouldn't no matter how hard we tried. I was wrong about the 1/2 inch hanging off, she said it was about 2-3 inches off. How did you get yours to fit? Also in the manual for the Nautilus it says it has to be all the way on for booster mode, but doesn't say that anywhere for harnessed mode. We were gonna call monday and find out why it is so important to have the whole base on. Right now we have the infant seat and True Fit RF in the back and the two Nautilus' in the 2nd row, but it is a pain to get the babies in the back, and the little one just screams the entire time he's back there and there is no way to get to him while the car is moving.
We also found out he is quickly becoming too big for the harness on the Baby Trend. I think I have it all the way out, and it is still really hard to buckle because it is so tight on him. I might get a Marathon from a friend here (girly pattern but better than him being squished in his baby seat.)
The tech said I might have to get new seats for my older kids if I want to put them in the 3rd row, unless Graco says it's ok for some hangover to occur. That would really suck because I just got these at the beginning of the year and had to wait until tax time to do so, there really isnt a way to get them new seats like that again without my husband getting mad.
