You need a good vehicle to make it to your bug out shelter. I hope that you would have a vehicle when TSHTF. I would not want to be walking in a time like this. The vehicle would be able to carry a lot of supplies that you have packed away for some rough times that you may be coming upon. If you really have the money you could always pull a bug out trailer too.I would like to have a vehicle that has a high clearance so I could roll over stumps and sidewalks if I needed to with out tearing up my bug out truck. I know the vehicle is going to be a gas guzzler but that is a risk that I will take. If all else fails I could just park it and hide it until I was able to get more fuel. It could also be a great shelter if you had a Coleman White Water Large Cool-Weather Scoop Sleeping Bag
