Perhaps consider a Suburban or Yukon XL. With the 3rd row in place there’s very little storage room in a Tahoe. I think it’s easier to find the hauling and payload limits you’re looking for in an XL but If you go with a Tahoe and the bench seat your family will fit in 2 rows. I guess it all depends on how often you need extra storage and if your young ones can sit next to each other on long rides.
