Thoughts?

It will be for LO #1 when #2 is ready to switch to a convertible so I'm not concerned about RF.

They claim Radian R120 fits 3 across does the RXT not? What's the biggest difference between the R120 and RXT?

The biggest difference from the Frontier and Radian to me right now is the Radian is FAA certified whereas the Frontier is not. But honestly, I really don't see a ton if any flying in our future.

Our convertible right now is Britax Marathon so I am concerned about being able to seat a passenger comfortably with another seat in the back. But I'm wondering if that's a pipe dream in any vehicle unless we go to a minivan?
