Eugene: "..whether or not those in charge can take things you bring with you to distribute to those without."
That seems to be a frequent worry, but I've never heard of it happening. They may be happy enough that you're not a drain on the supplies, and it's hard to see how one person or even a family could bring enough stuff that it would be worth the confrontation.
Coastie09: "If you need to provide all that equipment on your own, it sounds like going to a shelter is useless..."
While most of us here would probably avoid the shelters if possible, many people that have the 'stuff' might be too scared to go it alone, despite the disadvantages. And if you're facing something that requires a shelter (hurricane, tornados), you may need the actual shelter, and when the event is over, you can leave with your gear.
KC2IXE: "...they get a truck to go from B to A with food and TP, and back with cots."
Have you ever seen where the trucks couldn't get through? I'm thinking earthquake debris, high water, etc.
MajorMarv: "Susan do you recommend the book ?"
Overall, yes. There's stuff and methods that we at ETS think of as SOP, that she doesn't cover, so I wouldn't say it's a what-&-how-to bible, but it does cover a lot. The people new to preparedness would have a lot of good information laid out for them in a reasonable order. I would buy it if I could afford it ($40USD).
Re: the pickup trailer. My brother wants to put together one of these. Other than the advantage of cannibalization, it seems there are better ways to go. I've camped in the back of a pickup with a shell. It's not too bad for one person, if you have a 24-30" wide piece of plywood from side to side behind the cab for gear, but for family, no.
If you look at one of those trailers that have a flat floor without the wheelwells, there is no comparison in floor space. And if you customized it with folddown bunks and storage, you could carry an incredible amount of gear AND house your whole family. And if your tow vehicle had a camper shell on it, you could carry even more.
