This is a question for the cps's or any fellow parents who may have experience installing convertible car seats in different vehicles...i'm looking at the graco my ride, the first years true fit, and the radian xt/premier/65 (or any of the other radian models that are similar in size) ...we have the 2005 Rendezvous but i'm sure any year would do ...my only option for ordering the radian or true fit is online so i would love to know that someone has been successful in installing these seats correctly in my vehicle before i order one...i found the my ride at walmart/toys r us but I would rather not have to exchange a number of different seats if all I had to do was as for help from all of you ...thanks so much
