Need car seat that will work in Dodge Caravan and Toyota Corolla

[HonkyTonka]

Would love some input on which car seat to get for my 8mo LO. Here are a few details:

She's in the 85th percentile for height and weight and has chubby thighs. 

We only want to buy one seat and move it between the two vehicles when needed.

The van has bench seating.

We visit my parents a few times a year (10 hour drive) so the seat should be comfortable.

I plan to keep her rear-facing as long as possible.

I've gleaned (from some other posts) that people really like the TrueFit, Radians, MyRide and complete air, and Evenflo Triumph65.

Do any of these fit my needs more than the others?

I also noticed that the Britax Marathon 65 is on sale here ($90 off) and I've heard that Britax is a good make.

I really appreciate your advice.

I'm not a car seat expert by any means, but my two year old has been in a true fit since he was 5 or 6 months and we really love it. It is comfortable for him and I am able to get him in and out easily. It is a big seat, but I have kids on either side of him in my SUV in boosters with plenty of space. Just thought I would share that we have been happy with this seat. Good luck with your search!

My DS is 4.4 and he is in a True Fit. He was RF-ing in it until 3 and is FF now. We also travel approx 10 road trip a couple times a year. He loves his seat. I drive a dodge caravan as well.
