I'm rewriting my whole post.
Is it ok to put the convertible seat behind the drivers seat?
To Summarize:
I have an 04 Mazda3
I have a Britax Roundabout
DH can't fit in the car w/the seat on the passenger side or in the center.
Manual does not indicate which side, if any, is best.
carseatdata.org does not have any entries for my model year and specific seat.
Re: Ok, ignore my pp. Which side should I put the carseat on?
The Britax manual says to use it when RF, w/a tether anchor point on the floor.
center of the car is always the safest for placement of carseats
