Hi Clover,

I know this isn't a Prado but we recently needed to upgrade to a 7 seater due to having a 4th child. I ended up going with a Nissan Pathfinder as it has a surprisingly large boot. The 3rd row seats are split fold so I have one child (in booster) permanently in the boot. Behind that seat which is up I can fit my pram which then gives me the whole other half of the boot. They have a really good towing capacity 3000 tonne. It is a 4wd but isn't huge so I find it easy to drive when I'm in town. We live on a farm so it has done a lot of km's 45000 in about 1 year and is going strong.

Good Luck with your search
