Traeger Com200 Question

[nakedpigbbq]

If anyone is using the COM200 Traeger unit, what is the most pork you have cooked at one time, and how much did it change your cook time? I need to cook about 500 pounds of butts to net the 250 I need for a picnic, and am thinking I will want to divide this up and have it precooked. I always cook the butts in pans, and not sure how many I could fit on the shelves.

thanks!
