Anyone install seats in a 2011 Sienna?

I need to install some seats in a 2011 Sienna and I'm curious about how big the 3rd row is and what will work there. I need two forward facing car seats to fit plus be able to fit another child in the row. Would two Radians work? I'm trying to prepare before I get to see the car.

So the 2011 only has three top tethers. If I have to put two Radians back there then one will be untethered. Would you rather your child be in a non-tethered Radian or should I try to booster train him and put him in a PWSG. By the time we start carpooling with this family he will be 1 month shy of 5 and is about 47 lbs. If I insist he sit in the tethered Radian, I'm sure the mom will let him but her younger, smaller 4 year old will then be boostered. This seating arrangement would be for 1 trip per week.

I had a 2011 as a loaner overnight. I didn't measure the back seat, but it looked like it was about the same as previous years, except for missing the passenger set LATCH set.

If it's the same size as the older model, then you can get two radians on the driver's side and in the middle. Then most any other seat or booster will fit on the passenger's side. I'd let my kid ride in an untethered radian. It would be easier than trying to get a new booster rider to be able to buckle a seatbelt in a tight three across. I'm more comfortable with the untethered radian.

I'm pretty sure my best friend's Sienna is a 2010, and there are 2 tether anchors behind the third row (center and passenger, if I remember correctly).

We fit a Britax Marathon and an EFTA side by side, forward facing, last summer.

I'll double check the pics--maybe it will show how much room there was left on the other side of the MA.
