I didn't see if your 'Tour is a V6 or not. I did the oil pan gasket on my V6, and it wasn't too hard. I hadn't done anything like that before, so it took my ALL day (I did have a tool issue as well which killed some time). You do have to take the Y pipe off (3 spots), then drop the pan, remove the old gasket, clean (I did anyway) out the panand the pick-up, re-RTV, new gasket, RTV, then put it back up. While I had the Y pipe off, I replaced the nuts with stainless ones from the hardware store. Should slow down the corrosion...
Good luck. It's not too hard, but was time consuming for me. DEFINITELY use a lot of PB Blaster (let soak a day or two, and reapply) for the Y pipe nuts.
It worked for me. No leaks now! If I can do it, pretty much anyone should be able to, and I'm SURE it would take less time!
