Get them used to being tied out before you go. Tie them out during the day and put them in the box at night if needed.

when I go to east tx with my dogs, I may tie out during the day, but most of the time I just let them run the property and then at night, I put them in the pig wagon, which is big enough to hold 5-7 dogs comfy.
I seen a guy do what kevin is saying about the long chain. he would run a 50-75' chain from tree to tree, or stake to stake and had 5' leaders off that spaced every 10-15' of so and tie his dogs off to each leader.
