After a little more research, I decided to order a cover from
Car Cover USA. They have covers specifically designed to fit all Crossfire models and they cost less than the Mopar cover from Wyckoff. I'm also going to get a
CarBag to keep critters out. CarBag doesn't list the Crossfire but I believe sizes M1 or M2 should fit. I'm going with the larger M2 just to be safe.
