I would think if she did have a will, the attorney or the person she named to oversee it would be the one to contact.
Also, maybe present to her children something like auctioning the truck, dividing the proceeds between them along with a percentage being donated to a charity in the name of Dawn and 67-72chevytrucks.com. Perhaps a charity that Dawn may have been affiliated with or given to in the past. Just a thought as perhaps it's much further along than this already.

An update would be appreciated.
