I know I am coming in late here on this topic but I have had a XL BGE for two years now and love it , I added the BGE while still keeping my Weber Genesis for quick grilling. Most recent accomplishment was thisz years Christmas turkey 18lb bird cooked over Wicked Good lump charcoal and Ozark Oaks Lump ... tiny bit of applewood for a little smoke ( didn't want to overkill it ) cooked at 350 degrees AND came out amazing for the family.
I have used it for everything and really do recommend one for anyone who loves to BBQ and Grill. They are the ulitimate versatile backyard cooking tool .
I did a 12# turkey last sunday, using cowboy ( goodlump from the bag don't like the chemical smell) Did it in a Brine and 2 handfulls of applewood with apple in the cavities. The best ever nice smoke ring. It looked like I was cutting a sponge soaked in water. I was a bourbon red turkey the smallest one in the freezer next on with involve the bourbon some how.
my bird cooked at 200 (4.5 hrs) till I stoked it to 350 for another hour. It looked like peking duck on the out side.
