What Walmart does when putting brand new trucks in service, ones that have been towed in and not driven, is to run them in high idle for a good long while.
The smells coming off these trucks are atrocious because of all the stuff burning and so on.

Oh, and since you've got tank heaters and a cow catcher, and don't believe in washing a truck, and while I assume you'll run up north in the winter, here's a few pictures of what a month without a wash up here looks like.
