We recently got a 2011 Honda Odyssey and are having a really hard time getting a good install with our Diono Radian RXT. It is drivers side, second row, RFing and since we have added the angle adjuster the whole setup leans into the middle terribly and isn't as tight as I am used to having a seat. In the past, I have always been able to get rock solid installs with all of my seats (in my '05 Dodge caravan) but I can barely get under the 1" movement with this seat in the Odyssey and again, it leans significantly towards the middle. The issue seems to be the contouring of the seat, but others seem to be able to manage to get this configuration to work so I am not sure what we are doing wrong. HELP!
