As a fellow Texan, I love grilling. Most of mine is done for dinner though. I have a dual grill with 3x burner propane grill and sear burner on one side and charcoal grill with a smoke/firebox on the other side. I picked it up for less than $250 on sale at Academy. I made some attempts to seal up the holes to get a better seal for smoking purposes, but I never got around to fabricating a baffle. I tend to always use charcoal (B&B) and check the fire every 20 minutes or so, which gets pretty tedious for a 8+ hour smoke. I grill steaks and burgers and chicken a lot more often.
