La Caja China - Cooking a pig

[TornACL]

In preparation for the Arkansas game/tailgate/pig roast this year, our group plans to do a practice run in a few weeks.

We have one of these: La Caja China

1) Anyone ever used one before? I watched my brother in law roast a pig a few years back, and it seemed fairly easy, as memory serves.

2) Any other general tips / suggestions / hints for a successful pig roast?

I think I saw Bobby Flay use one of those in a Throwdown. No tips but it did look interesting.
