Ive decided to take no chances from the start here. I have decided to order the hitch lock vault for $90.This appears to be the best option all the way around.This covers the entire hitch and cant be removed,even with sledge or crowbar.Unit is loose around the hitch and prevents a clean strong entry of a crowbar.This unit covers the hitch and prevents removal of the tongue from the bottom.I would hope that would be enough to discourage would be thieves..Since Tennessee seems to be up there as far as trailer thefts,I am also purchasing an 8 foot logging chain and the heaviest lock,tractor supply offers. Both for $75. Also 4 boots to attach to the wheels. I will attach the chain through the heavy steel supports for my car port. I don't think anyone will be able to steal it then.
