Our Crossfire is kept outdoors with a cover on it. I have an old cover that is no longer good for outdoor use (it spent a couple of years in the Florida sunshine and I hand re-stiched a few seams - it's not pretty), but would be fine for a dust cover in a garage. You are welcome to it if you want it (you pay me back for the postage when you can). If you want it, PM me with your address).
New covers suitable for outdoor use are fairly pricey. I went through Cabelas for my latest cover.
