I'm building a grill/smoker and have no experience at building a grill or smoking. attached is a photo of what I'm building and am looking for sugguestions to add before I get to far along. In the photo I have a LP grill on the far left for the quick stuff when I'm tired after work, The center will be for grilling by charcol and fire. The right is the smoker with three racks and the smoke opening is at the bottom of the center where the fire pit will be. The top covers and doors are being built, I still have to fire brick the center and add a damper. This started off as just a grill and then got a little outta hand. Thanks for any sugguestions.
