I was reading an older posting regarding Bug Out Vehicles, and it seemed to be oriented towards 4 wheeled vehicles. Four wheeled vehicles have a lot going for them, such as the ability to haul large loads of gear and equipment, the ability to tow, and improved protection from the elements. My first choice is a four wheel drive SUV, however I like to have a plan B, plan C and perhaps a Plan D. Using a hitch mount on my SUV, I also carry a Yamaha dual sport motorcycle with attached hard cases for gear. I've used the Yamaha for camping in the back country, and it's capable of transporting a fair amount of gear. It is fully off road capable, yet will still run at 60 mph on the highway. It is somewhat EMP resistant, as it uses a carb for fuel mixing. If it gets stuck in mud, it is easy enough to get it unstuck. The only drawback is the size of the fuel tank, but it's easy enough to carry additional fuel cells. That's my plan B. Plan C is to resort to good old fashioned feet and hoof it to my final destination.
My plan D entails the use of a Ural two wheel drive motorcycle with a sidecar. Older Ural motorcycles have carbs and are very basic, so they are simple to repair. There's not much plastic on these machines, they're constructed of steel and they're very rugged. They're based upon a BMW design, and the Russians reverse engineered the machine and have manufactured them continuously since WW II. They were designed for war, and mine includes a mount for a machine gun, extra fuel can, and an extra tire. They can transport two passengers besides the driver, and they drive well in the snow and in mud. At this point parts are readily available and I've stocked up on some spares. Dogs love the sidecars! I've attached a photo of mine.
I'll also be adding a small aircraft for a plan E. The problem with aircraft is they're easily effected by weather conditions, and landing areas can limit usefulness. Used two seater fixed wing aircraft can be purchased in the $20,000 USD range. But one needs to maintain flying skills and also ensure that regular maintenance is performed on the aircraft.
Anyways, I thought I'd offer a few transportation alternatives, and I'm sure folks can come up with many more.
