Just wanted to say thanks for all the advice from those that chimed in.

I ended up doing a mix of a lot of things listed above ... wheels on wood, raised tongue to help run off, sprayed rust treatment oil on hitch / electrical items, pulled battery, bagged the hitch and the wheels with heavy garbage bags. Trailer is locked, insured to the hilt, and is parked in a very hidden, remote part of the property so theft shouldn't be an issue.

Thanks again everyone,
Cheers, lgb240
