Help need - 22lb pig - need instructions
 

So I got a 22lb pig tonight for my birthday from my parents - talk about a fun gift.

Had a bbq party tomorrow anyways, so now I want to cook this for tomorrow.

I have a XL BGE and I measured the pig curled in the fetal position and its less than 24'', so I think it will fit on the grate w/o a problem.

Question is on cooking time and temp. Cook straight on the grate, or should I wrap in foil then put on the grate - again, cooking in the fetal position.

I may inject it tonight and have it sit on ice in a cooler and cook it tomorrow - just wanted to know approx how long it should take to cook.

Dinner tomorrow is at like 6pm, figure it should be done by 4ish so it can rest for a bit.

Thoughts?
