FWIW, I like the last option best -- "...a beater like a Datsun or Toyota truck until I determine a permanent solution."
Getting a cheap disposeable may give your self some time to sort all this out without having to rush. Sounds like you are under some stress.
I once bought a throw away disposeable vehicle (at auction on kind of a whim ....) and I've liked it so much, its been my DD for 5 years now.

I'd never been a van guy but I have been amazed at just how useful they are ...
