My survival plan consists of 50 some years of living off the land. There are just so many possible emergencies; flood, draught, earthquake, storms, invassion, civil unrest, etc. You would need a bookcase of plans, and if you are not self reliant, none will be of much bebefit.
My RV is not even a consideration, I will shelter in place, good for about 6 months before I would have to dig a well. The only limiting factor is my health.
Most of the preppers I see on TV wouldn't last a long weekend.
