Collector; my van is my "bob" like your truck. I hate vans, but after getting this thing, it has been immensely useful. If you have to, two can sleep inside the van without difficulty but you need to move your "stuff" to make room.
The need for a generator is relative. If you have one, it provides at a minimum power for some electric lights. Even the really small ones will handle this task. There is a lot of "comfort" knowing that you have the ability to have some control when facing an emergency. Contrary to you, I think there is not substitute for a generator. It takes all of the doubt about frozen or cold storage of foods. Long term, there is a fuel issue, but things get righted slowly after a regional disaster.
Relative to Sandy, my brother was out of electricity for 51 hours, other brother out for about 40 hours. Certainly not like many are facing in NJ now. He (51 hr brother) borrowed a small generator and it provided sufficient comfort that he immediately purchased a larger generator as soon as he could locally which was the next day. He stood in line at the store and they stayed open until they sold all that they had in stock. Now he is going to have an electrician install a proper connection beside his regular breaker box. I am going to do the same thing. Eventually I will get a larger than 5500w generator, but for now, it will do nicely. My 40 hr brother is also going to do the same thing as soon as it is practical.
When you have a predictable emergency such as a hurricane or storm event, you have warning and you should fill the tank of every vehicle you own which serves as a resovoir for fuel for generators and so forth. Also fill all of the gasoline cans and if winter, and you have the capability to use kerosene, fill those containers up. For me, kerosene is one of those things that I put off as I have little use for the stuff other than in an emergency with the one kerosene heater that I own. Once you have filled containers, what are you going to use all the kerosene for? You can't dump it into your cars. But in the winter, I do use one of the jet kerosene heaters at work sites and occasionally my garage.
