If you have willing friends or family, occurs to me that it would be great to have an RV -- travel trailer, perhaps -- stored somewhere and have it stocked (carefully, to guard against rodents) with canned and freeze-dried food and some camping gear.
.
Provided you can keep the RV in running condition. My next door neighbor's landlord has a RV parked in windowsill high weeds. I suspect they use it for storage because the tenants aren't allowed near it, and their primary residence is in a fire hazard area. I would be very surprised if it's still capable of moving under it's own power (It hasn't been started since we moved in 8 years ago).
OTOH, an enclosed sport or small utility trailer requires much less upkeep then an RV.
