We've been storing our TT's at the county fair grounds for 10 years this winter. They put the campers inside the different pole barns/buildings in mid-Oct and they don't come out until mid April snow-cover permitting. The buildings and grounds are locked up so I can't get in to check on it, but then again, nobody else can get in either. If the locked gates and buildings don't discourage the 'riff-raff', trudging through 3' or 4' of snow for about a half mile definitely will.
We stored our 2005 every winter we had it until we sold it this past spring. Our 2013 Eagle 284 BHS goes into winter hibernation on 10/11.
