It must be a Sith thing.
Darth Vader has his hyperbaric chamber where he has to scuttle away to whenever he wants some time alone. Perhaps that was an artifact of being julienned by his ex-teacher, but when I read about Darth Cheney's little hideaway, I begin to wonder:
A mobile home trailer. In a C17. It's bad enough that the Air Force is naming the C17 the "Spirit of Strom Thurmond" (I suppose calling it "Executor" would have been a bit of a giveaway), but using it to carry a trailer? Either (a) Darth Cheney is even more batshit insane than I thought, or (b) he's one of the aliens from V and he wants a little hideaway so he can peel off his Jabba the Hutt suit and relax.
