I park mine just as you describe. I have a cover on it and a trailer lock on the tonge. I haven't had any trouble in 3 years that I've had it in it's current parking spot. When I lived in Seattle and primarly fished the Yakima, I had it parked for a time in a self storage facility in Cle Elum, Norris Storage. I also, for about a year, paid a nominal fee to one of the fly shops out that way to park my boat in with their fleet.
