Wife switched to a minivan when we had our 3rd. I'd suggest seriously considering with the following set-up:
- Fully remove the end seat in the 2nd row (you can easily do this in the Odyssey, not sure about others).
- Older kid just steps in and sits in the 3rd row.
- Removed seat is on the passenger side so the kiddo can easily just step out from the 3rd row for school drop-off.
- You can easily add the seat back for the 2nd row for additional passengers on a family trip.
Your issue will be the fact that you're a giant! At 6' 2" I can easily manage in the Odyssey but you may have some trouble with rear-facing seat + leg room needs. You can have the "open seat" on the driver side of course, but that would never work with child drop-off.
I switched to an Expedition EL/Max not long after that. Yes, 3 kids can fit across the second row of a crew cab, but anything you'd need to keep in the car for a moderate trip is in the floorboard. It's a mess.
I agree the bucket seats are a good idea for the babies. You will NOT to be working with the 3rd row in a rear-facing seat. After the removable infant car seat, you'll be heaving a kid over the top of a rear-facing child seat. Add to that, you may struggle with a rear-facing seat in the bucket behind you as a drive...the whole giant thing again.
That said, a 60/40 might work in a 3-row set-up with one of the kiddos in the middle of the 2nd row. Some are removable on the end. It just domes down to preference and the hassle you're comfortable with.
If you travel much at all, consider the storage room you use now and then more than double it. Every baby we've had we somehow have to relearn that there's just a bunch of $#!+ you're hauling with them. Pack and play...diaper bags...diapers x TWO, etc. You'll have to decide whether you try to get that room from behind the 3rd row (Suburban/Yukon XL/Expedition MAX) or do you utilize a hitch hauler or roof cargo. With our Expedition EL, we've just said screw it and done all 3 so things aren't piled up behind the 3rd row.
Have fun!
