We have the 61 with a couple minor changes w/cabnets & such and it is perfect for us.
(my wife and I + 3 kids 6 to 10 yrs old)
The kids love the gaucho and there are NO issues with anyone getting car sick which we were told can happen with kids sitting sideways with the 61 layout.
2 kids can sleep upstairs and they fight over it. The coolest thing they've ever seen.
We take the gaucho and the other sleeps in the fold out dinette setup.
You could sleep another young child in the dinette and we may try it a time or two but thats getting a little tight for sleeping. This wouldn't even be an option with the 60.
Realistically 2 adults and 2 to 3 kids is perfect for sleeping.
For driving there is plenty of room for 7 easy.
The walk through plan makes it very comfortable and open and storage is pretty good under the dinette.
