Had a RXT installed rear facing (with angle adjuster) in the 3rd row of my Sienna. A friend's 2 year old rode in it while we were visiting in July. She liked his fit so much that she got one. She just installed it in her Odyssey (with angle adjuster) and he seems to fit so differently. He was above the 3rd (I think) slots in my van, and he's barely above the 2nd slots in her van. Is it possible to loose that much height from 1 vehicle to another?? The. It gets issue she has with fit is because now the headrest isn't low enough for him, whereas in my van it was perfect.
