Haven't had an official bullet proofing. We won't spend the time or money to get it done now which means you save the $$ too! We have all our service records for the amazing work our mechanics have done to keep our engine healthy and happy.
For everyone not wanting to click through: 2006, 4x4, 6.0 with 216k on it. Doesn't look like there is a fridge. Has propane. Looks well cared for and loved. No indication of any bulletproofing.
