I second @Heckraiser 's comment on a full size domestic van. My buddy has one for family camping and it works great (his has the 4x4 conversion completed). We both just bought hard shell roof top tents which adds that much more space (this photo was from a few months ago before those).
The 80 would be great as well, however if you are purely looking for something to camp in I'd go bigger and or with a trailer. A trailer can be packed and ready to go at any time.
