Hi all!! I'm desperately looking for a spare tire cover for my newly renovated 310 series which will be hitting the road in two weeks. Does anyone know where I may be able to find one and purchase asap? Or if there's another version that will work? Or have any creative ideas on constructing one? It's such a great place for me to promote my biz while rolling down the road. Would love any input on this! Also, how much I should expect to pay?
