Well I went simple but its functional...just a couple small drips but holds water well...only lost about 1/2" in 24 hours.

hey Kevin...you probably will need to nail a couple more boards across the top otherwise the pigs will lay in the trough and push some of the water out as well as muddy up the trough...as a kid we built the troughs smaller and the larger ones had boards across it to keep the hogs out...
