As far as covers go... Green Mountain Grill has tailored a nice cover for your investment. They've built and tested a form-fitting grill cover to withstand the toughest weather conditions. Velcro cinches secure the cover to the grill keeping it safe and dry. Don't let your grill sit outside baking in the sun or drenched with rain and snow!
For the Davy Crockett's; they not only have covers for it but also two travel totes; Black and Camo.
And for you cold weather climate smokers... GMG Thermal Blanket is a great way to protect your pellet usage.
