A dissenting Opinion
Couple of things: Define your use case:
Is this a daily driver or long distance adventure/mutli-sport vehicle?
We have a mildly built 2007 Jeep Rubicon 4door...
1. Rear facing seats will need to be put in the middle...unless you want to be in the dashboard. If you are taller than 5' troll, the rear facing seat will not allow front seats to be slide back & be titled properly. I'm 6' and have a large frame, wife is 5'8" with longer legs/arms than me...she's a competitive figure skater & recreational runner and I have lots of sports injuries - we need to have the ability to stretch/move otherwise we are both miserably (me: back, hips, knees, neck; her: hips). We both love mtn, road biking, hiking & kayaking...
My 10 mo is >100% for height & weight. He grew out of his Briax seat at 4.5 months (length) and has been now in a Clek Fllo for quite a while. We tried all the various seats and cant imaging having a convertible car seat (while still rear facing) behind one of the front seats.
2. We travel...a lot...on really long trips.
We traveled from CA to ME (and back) with a 2.5mo (our on), our 90# St Bernard mix, and was full of outdoor gear (all backpacking style). We travel light and are minimalist. It was still very tight. We took a Fridge/Freezer to stockpile breastmilk & save money while traveling. I put a rack in the back (above the cargo area) to maximize space.
PM if you want more details. We were on the road for 7wks and 11k miles...in the heart of winter. We would do it again in a heartbeat....but honestly would prefer a larger vehicle to do it again. (See Number 5)
3. We now use a small offroad/jeep trailer when we Jeep camp...not that we need to, but it is infinitely more comfortable - less stress of trying to make sure the dog has enough room, our son, etc.
3.5 A large hitch rack has been a life saver for short trips when traveling with the dog, a Bob stroller, and misc gear. Again - not cause we need it, but because it makes it easier to get access to all the various gear. I have gear appropriate crates (which gets used a lot) to store on the rack...and will strap bikes to it as well. But most times, we opt for the small trailer - more space, more comfort for everyone. (NOT more crap...)
4. Be careful on the sizes of the stroller - look for the more compact strollers. We kept things small/light and are happier for it (except for the Bob ... we like the big tires for fire road/gravel hikes). My wife can visit her folks on the east coast with just a carryon (for her & the baby).
5. We love the Jeep - but are looking for a full size 4x4 van (e350 or sprinter) to replace the Jeep as our primary fun trip vehicle...The Jeep will continue to be our short trip/my DD - but the van will ultimately replace the Jeep as a our adventure vehicle. The jeep is just too small for our long distance/multi-sport/multi-season adventures. We travel any time of year, in any weather, for long periods at a time.
We are planning on a 2nd child and will be adding another dog too. Jeep is just too small to be comfortable with all those car seats & dogs - and travel comfortably. There are few places I will take my family where a Jeep is the only vehicle that can traverse a trail - most places, a built e350 will be fine. A 4x4 Sprinter will get into fewer places, but at the moment, I'd rather be happy for 99% of the trip than the 1% where only a Jeep can go.
