If you need a large passenger bus to fit your Duggar lifestyle (or if you are starting a band, church, cult, etc), you might be tempted to pickup something used from the private shuttle bus market, used school bus, or ex-public transport, but you'd be wrong. The thing you actually need is a used prison transporter like this 2007 International 4400 offered here on eBay for $18,900 buy-it-now located in Hollywood, FL with 18 days to go.
If you aren't in the 50 percent of DT readers that have huge families or cults to transport, you might wonder why you'd want this. Street cred notwithstanding (put a Dept of Corrections sticker on the side and nobody is gonna mess with you...ever) this thing looks perfect to transform into an RV or apocalypse survival vehicle. Those skinny windows that don't let in much light and stop perps from going all Hannibal Lecter on random pedestrians will also help keep out the mindless undead when the zombie apocalypse is upon us.
Apparently the cons who ride inside don't get seat-belts, as an uninitiated, I would have assumed each seat would come with a place for shackles or something you would find on a Roman slave ship, but only the guy with the shotgun gets a belt. At this point you might be thinking to yourself -- it will take some time (and bleach) to fully clean the inside of human fluids, but you haven't seen the bathroom yet...
This bathroom features a heavy duty lock on the door, but it isn't clear if it is to keep people in or out...but it would make a great place to leave your best friend after he has been bitten and waiting for him to turn. Eventually you'll have to whack him, but the heavy duty door should keep him contained for a while.
