[OoC: If you plan to use the boxes as a bridge...]
You all line up the boxes and thread the rope through the metal loops. Then while everyone holds the opposite end of the rope, someone pushes the 5 large crates into the river. The current attempts to drag them down river but with a group effort you're able to stabilize them to tie the rope to a sturdy stalagmite. Taking a moment to examine your handiwork you imagine you could use the rope to help guide yourselves across your stepping 'stones' but the crates are still not particularly stable. The metal loops were meant for tethering the crates together and guiding them downriver with a boat. Not to make bridges to walk across.
[OoC: I'm going to say that you only need to make one balance check. But the current DC is 8. Then you add your Dex bonus, armor penalty and any synergy bonuses for having 5 ranks of Tumble. If you can think of anything else to help lower the DC, feel free to mention it because every little bit helps.
Tomeal's bonus/penalty would be -4 (armor) +2 (dex) = a penalty of -2. So DC10. Ummm I think he's going to be removing his armor to get across this river. So his new DC would be 6. Still kind of high...]
[OoC: If you decide you're going to use a box like a boat...]
Your group prepares to use a box as a boat to ferry yourselves across. You thread the rope through the metal loops for extra security so the box doesn't get washed away. Now you must find a way to get into the box from the river's edge as there is a gap of about 2.5 to 3 feet to cross. A couple of obvious ways into the box is to climb down the steep river's edge a few feet to reach the box and then climb into it while it's bobbing on top of the water or jump from the edge of the river into the box while it bobs in the water. If anyone has another suggestion then feel free to offer it.
[OoC: The DC of this option will be determined when you decide how you're climbing or jumping into the unsteady crate. Remember the surface of the river is 5' down from the river's edge where you stand. A 5x5 crate floating on the river will leave the top of the box almost as high as the river's edge with a gap of 2.5 to 3 feet. If you want to put stones in the box to weigh the crate down deeper in the water that's up to you to determine how much weight you want to put in the box.]
