got a lil holiday spirit in me last week and went off and bought a 16 lb turkey and told the family, "hold on, i got Christmas dinner"........w/out thinking "i've NEVER fried one"

so, it dawned on me again TODAY -- dummy, you've NEVER done this.....
as such, and relying on the wealth of knowledge this dump can offer.......
any tricks to it? i've got 2 jars of that cajun injector marinade ready.....
you got a seasoning for the outside you like?
peanut oil, vegetable oil? which is the best way to go?
this pot can hold an 18 lb turkey, 30 qts, any idea's how much oil would be a safe bet on frying this sucker?
yeah, i know, we're gonna be ordering out about 1300, so save it

help please.....gator
