It sounds like he needs a small inflatable raft, & a dry bag just in case. I wouldn't count on Portland for anything! strike that I'd count on them making a bad situation much worseI live at my BOL, and as it is now, I only go into town, on average, about twice a month, sometimes less. Which is why I am not too concerned about fuel; even if I go into town once a month, I have enough treated fuel stored to last for years.
My immediate vehicle usage - if SHTF - would be to transport my kids and their stuff from their house (15 miles away), to my house.
My main concern I have is if we have the "big one" (Cascadian earthquake) and the bridges or the roads are impassable even with a 4x4. The two bridges between us are supposed to be able to withstand a severe earthquake - but who knows for sure?
Also, my SIL works in Portland, almost all the way north to the Columbia river. So if he is at work when the earthquake hits (50/50 chance?), then it will be an ordeal for him to get home. I've convinced my kids to have a GHB in their car, but I am not sure how diligent they are about keeping it there and supplied appropriately. OTOH, my daughter works from home, so the chance that she is there if an earthquake hits is 95+%.
What I am looking for is something to convert my truck to an RV for travel. Also for my pickup to flat tow and keep a dirt bike inside of a canopy over the bed, out of sight and I would flat tow behind my truck. Both vehicles would do double duty as a SHTF vehicle.
In the case of a SHTF event, I am mostly okay with what I have now - but it would be nice to have the option of a habitat on both the truck and the pickup.
