You only have one child?

If so, how can the KJ be too small?

There are people on here with three children and they feel that it is roomy enough.

You gotta do what you gotta do, but I can't see one child and his/her baby gear taking up so much space that you need to upgrade to a larger vehicle. I'd recommend packing lighter, if possible, but it seems too late for that now. Sorry you let go of your Liberty so soon.

I'll be buying a Honda Odyssey later this year, but only because we're expecting our third child this fall. After checking out various 3rd-row SUVs and "crossover" vehicles, a van is the only way to go comfortably and still have room behind the third row for more than one small suitcase. Minivans give you a lot of vehicle and safety features for the money! When we test drove the $31K Mazda CX-9, we couldn't fit anything other than our double-stroller in the back, and even that was a challenge. Any suitcases, pack'n'play, etc. would need to be loaded into a rooftop carrier, and if you've used one of those, you know that they're inconvenient for everyday use and will decrease your gas mileage on the highway to to wind resistance.

I transported my wife, 4-year-old, and 16-month-old down to TN in our KJ and had plenty of interior room. Our rooftop carrier held a stroller, booster seat, and various lightweight items like sleeping bag and pillows, leaving the Liberty's cargo area for our heavier items like suitcases. The RoofBag soft cargo bag held up well even in a few thunderstorms and is nearly waterproof (technically it's "water resistant"). It's really well made for only $50. Don't even bother with the $30 carriers at Wal Mart. They'll rip to shreads after 500 miles.

Luckily, I'm keeping our KJ because it's paid off. My wife will trade in her Mazda6, which is only 1 year old.
