My D-800 may be dead

Sorry to hear of this, Jack. You may want to look into carrying a special insurance policy on your camera gear - I have what's called an "inland marine" rider attached to my homeowners policy, and it supposedly covers "all causes" of loss. I got it originally to protect me against theft when I travel, but it's probably what you need to cover these kinds of accidents. I think some photography associations also offer something similar.
