Question from a friend -- engine immobilization

As a followup to this, I managed to get the owner of the rig to do a very simple fix. Said motorhome is now in storage behind a barbed-wire fence, and a couple large dogs, Kangal mixes (each weighing about 150-200 pounds) will ensure that the motorhome doesn't get moved or broken into.

Problem solved. Thank you all for the posts. There are a number of ways to skin this cat, but ultimately, the only real answer is to move the MH somewhere secure.
