I am torn between to styles, I have this 120 gallon LP tank and was thinking I was going to lay her down and have a fire box on the lower end and a door accross the top. But am also thinking about having her stand upright to have a more consistant heat. This tank is 48" tall and has a girth of 94" (just under 8 feet around) so she is stubby a little but has a good girth to allow a large enough cooking area. If I lay her down I will have 2 cooking grates, if I stand her up I will have at least 4 cooking grates. But I don't know the square inches of either but I think either way it will be enough to do what ever I want to cook. So what are the pro's and con's of standing her up with a fire box attached lower bottom side vs laying her down? My only thought is more even cook temps. Thanks for any input.
