"Best" is all relative with what you want. If you like the floorplan and can envision where everyone will sleep and how you'll "camp" in it, then go for it.
My first concern (without looking at the floorplan) is, if you use one, where a pack-n-play will go? Given you'll have night time and nap times.
Next is - is there a bunk for the 3 year old that you can put a rail on?
Is there room at the dinette for a high chair (there are cool folding ones) and booster?
Really take the family and spend a couple of hours milling around one. For instance, at RV shows- being a big guy, I sit on the toilet like I'm making #2 and I'll get in the shower. I want to have room to spread out with both of those things.
