We used to bring Diesel's crate with us camping but it was huge and a pain in the ass, last trip we just let him sleep in the back seat of the Patrol with the windows cracked open and he seemed to love it.

Seeing that a few kids are going can I suggest you buy them a ref's whistle when youre camping.
Just in case they wander away or get disoriented.
