There was (and I presume still is--I last drove past in 2006) a yard full of russian trucks just north of Gulfport, Mississippi, on US-49. Many were painted white and the story I was told was that some guy(s) had bought a bunch of them to fix up and sell to the UN. The deal fell through and that was the end of that. The story wasn't even second-hand, so take it with a grain of salt. I have no idea whether the owners were willing to sell or even if they could sell them--heck, I don't even know who the owners were.
Here's the Google satellite view:

The trucks have been sitting there since at least 2001 and I never saw anyone doing any maintenance, although it looked like someone was occasionally removing a couple of parts here and there.
For what it's worth...
