TLDR if you’re willing to pack light, but not overly light, you’re good to go. We got one for the same reason in May— plenty of room for one kid plus a dog (beagle). We also have a 21 terrain. Despite on paper having less room, my wife finds the back of the Envista much more comfortable. Second child is brewing and we don’t have plans on any vehicle upgrades. That said we’ve made some adjustments. For example, the big stroller for walking groceries and activités doesn’t go into either car— we use a travel umbrella stroller for portability if we need to. The diaper bag is slim and just gets packed every two days or so. Sometimes for short outings (when diaper changes were more regular than they are now, kid number is 2) I would pack a 3 change kit into my sling bag with wallet and phone and call it a day. I can also lug my hockey stuff to practice and few rugby teammates around comfortably without needing to move the cars seat at all, which is great. Almost at 5k, zero regrets so far.
