I've had my large BGE for quite awhile. I've noticed that the bottom gasket has worn off at the very back at the pivot point of the lid. I've also noticed that the smoke has started "to escape" all around it. I figure it's time to replace the top and bottom gaskets. Since this is the frst time I will attempt this right of passage, I would like to ask if there are any helpful hints that any of the eggsperts here would like to pass along to this rookie? It's the "dead of winter" here. I'm wondering if there is an ideal temperature to accomplish this task at? I will say "thank you" in advance for all the eggspert advice I hope that I am about to receive.
