Late to the party, but here's how I do it

Overnight on low in the crockpot:

The pork
A handful of whole cloves
A liter of ginger ale
Two onions.

In the morning remove the meat, toss the rest. Shred the meat and put back in the crockpot with your three or four bottles of your favorite sauce and some hot sauce (shameless plug for Choula sauce here). For some reason, I really like the KC masterpiece spicy BBQ sauce here. As it cooks you may need to add a bit more sauce to keep it from drying out

Back on low, it will be ready in another six or seven hours.

This is a good place to use the disposable crockpot liners if your crockpot has hot spots, makes cleaning it all up later so much easier.
