As mentioned, ADCO Aqua-shed covers are a favorite, and the size designated Hi-Lo is the most common choice. For my 2720SL, I chose a slightly smaller version (12295) because I feared that the extra fabric on the larger one would flap in the wind and rip. I was storing in an open windy parking area. The 12295 comes down not quite to the ground (less material to flap), ties down just as Dick mentions, covers the propane bottles, but does not quite cover the hitch.
Either should work well for you. Again as mentioned, the most important thing is to make sure the wrap is tight (no flapping), and you generously pad all sharp corners and edges. The batwing TV antenna turned out to be the worst for me. Check out
