Suggest adding a quick drain valve to the oil pan in place of the factory plug. Far less messy to change the oil, and you don't need to worry about the threads of the oil pan getting worn or damaged over time. I used a Fumoto valve. If you go this route you also need to add an external magnet to your oil plan next to the drain valve to re-gain the magnetic aspects of the factory drain plug.
Also, with regard to a drain pan, if you have a 4X4 you should be able to slide a 5 gallon bucket directly under the engine oil drain. Buy a 5 gallon bucket with lid at your local hardware or big box store. Drain the oil into the bucket, slap the lid on, slide the bucket out, take to local oil recycler/drop-off location.
