Been there, and feel your pain.

Here is my .o2. focus on what's important. No lives were lost, and your hot rod is safe. But seriously, no lives were lost. changed a little maybe, but not lost.
Everything gone is just stuff, and can be replaced. some of it was irreplacable, and you will eventually find some irreplacable stuff to take its place. The rest of it you will just replace in time.

It's all just stuff, don't fret too much over it. I'm assuming you DID have insurance, that will help much. Give the Red Cross a call also, they are a good organization.

What I did: I had a 12X24 shed on the property.. it used to be a country store. It has hardwood floors, insulated walls with paneling, and an insulated drop tile ceiling with flourescant lights. At the time it also had a reach in cooler. I spent the next week or so in my spare time after work, installing a tub/shower combination, water heater, sink and toilet. Plumbed it all in to the existing septic tank. Got a nice king size bed from the red cross, and we moved in. Lived in that shed for near four years while I rebuilt the house.

I used the insurance $ to pay off the property, and the personal property insurance $ to rebuild.

That was a rough four years ( at times ) but it's all behind us now, and the house is nicer ( and bigger ) than it ever was.

good luck.
