None! Mine came with the super cool/whatever Jeep Liberty cover. Zippers on the side would jam when trying to get it off. Then one night at about 5F + I had a flat coming out of Anchorage. The cover was frozen to the tire, cause snow blows up inside. I had been in my friends shop doing an oil/filter change, and "some" of the snow melted, rest turned to slush. Once outside it froze solid. Ended up ripping the cover on the perimeter to get it off. Not a fun night. It's still laying in the garage waiting for a proper burial. May not be an issue for some folk, but in cold/snow country it is more of a pain. Like TBJ said, a repository for all sorts of crap! Go natural!
