The Dealership that I bought my Winnebago Adventurer Roy Robinson RV in Marysville, Washington State ships Winnebago Adventurers via barge to Alaska every year. The Adventurer is Winnebagos top of the line gas coach! It is one of the best insulated gas coaches on the market. Unless the owner abused that coach in storage ( leaks that weren't fixed or leaving doors or windows open etc.) the RV shouldn't have any troubles at all with be stored in the winter. The tires I've never heard of. A non collision accident could be a tree branch falling on the coach while it was parked. A title search of previous owners could revel more info on that coach. Good Luck
