Something diesel, gas will be to hard to find, even the conversion to run off cooking oil, lamp oil, etc,....
For me it would be a boat, with 671 Cummins Diesels, maybe Duetz, no computer control , simple to maintain, they run on broken valves, cracked heads, and almost no oil pressure.
Sail back up, need to get off shore for a while and island hop until the survivors organize and some communication can be restored.
An old Bertram would be fine. 34-42 feet. I would have the name "Eat Me" on the transom.
