Glen Canyon...
If you have time, I would highly recommend a kayak trip down Glen Canyon. I spent a couple of days paddling/camping along the river from the dam down to the start of the Grand Canyon last year and it was a spectacular trip.

Assuming that the dipstick tube location allows you to get the extractor hose to the lowest part of the pan, you should be able to get virtually all of the oil out.
Done this many times on boats (it's pretty much the only way to do an oil change on most inboard engines).

Try Mumbly's Off-Road in Fraser (Groesbeck near Masonic). Not sure how much experience they have with Toyota's, but they've been around a long time and have a good reputation.
Changed the oil (1st time on my new truck. Thanks Antman!) and made a poor-mans sleeping platform (the carpet is actually a lot darker than it looks in the pic).
