The GOSM Big Block dimensions 36"H x 24"W x 16"D (I'm not sure if that includes the legs or not -- if anyone knows, please speak up). So far, I've only seen three covers that will work, but none are ideal. The Smoke Vault cover doesn't have any of the features most higher quality covers have (elastic, draw string, vent, etc.), and besides, it won't cover the legs (not sure if this is a big deal or not, but I don't see why the legs don't need protection as well). Also, depending on if the legs were included in the diminsions listed above, it might not even cover the whole body. There are two covers from the Cover store that look like they would work, but nither have an ideal fit. http://www.the-cover-store.com/Searc..._smoker_covers 1) Kettle Cover: 29 inch diameter, 34 inch length. With the extra depth and width of this cover, I'm sure it would cover the 36 inch height of the GOSM, but that's only if the legs are included in the dimension listed above. 2) Smoker Cover: 32 by 32 by 40. With the extra size of this cover, I could probably use it to keep rain off the propane tanks as well, but it would definitely be swimming in it. This is the cover that I'm leaning towards though. Any thoughts?
