The Hemi is probably the easiest engine there is to change oil on!!! seriously!!!
They even have the filter mounted in the front of the engine where you can get at it and it has a nifty drain ramp so the oil goes right into the pan. The filler neck is large enough that you don't need a funnel, just pour right in. I know that it takes some time and you gotta laydown and all, but when your done, you know its done right. The hardest thing to do is greasing the cv slip joint on the front drive line (4x4) but that only takes a minute or two. You can easily change the oil grease the two zerks and the cv in less than an hour. Plus while you are down there, look around and see if anything else looks "funny".
I did mine yesterday and found that the master cylinder reservoir has a small leak coming out of it, and the zerk on the passenger side doesn't seal up after its greased. Isn't warranty great!!!!

 

I make so much fun of my friends who don't change there own oil. Don't be that guy.
