The appeal of having something ready to go, packed with your necessities and able to provide shelter, that is small and light enough to be pulled by just about any vehicle with a trailer hitch, is not something to ignore. I wish the prices were cheaper though. Or you could find one used for a good price. I'm afraid I am not handy enough to make my own, as many folks apparently do. We have trucks and vans too, but those are used to haul other stuff (and people) around routinely, so they can't be permanently stocked as an "always ready" bug-out-vehicle. One of these little trailers is ideal for that use (other than the cost).
