How to move and transport an 80 gallon compressor?

I'm looking at a decent deal on a vertical 80 gallon compressor on craigslist and the specs for the compressor read that it's 600lbs. I have no access to any sort of forklift, tractors, pallet jacks, pulleys from the ceiling or any equipment like that.

Anyone have any ideas of how to get this thing on to the truck and back off of it at home? I'll probably only be able to get help from one friend of mine but he's about twice as strong as your average person so that'll help a bit. I'm thinking maybe remove the motor and pump and then try and muscle the tank in the truck and just leave it laying on its side? Still that's probably going to be somewhere close to 400lbs so I'm not even quite sure if that's doable since my truck is a Tacoma Prerunner. Any ideas? You guys are a heck of a lot more creative than I am when it comes to this stuff.
