Have a road service contract anyway. You might be surprised that they will come out to help you in a remote place, as long as you can have cell service or a sat phone.
Give Coach-net a call and ask them about the service they offer in that area.

have a welder alum weld a lightweight bracket to a rear rv ladder if you have one. Fabricate a boat winch to the bracket. It will be plenty strong for one time you might need it.
