THAT'S what I can't find. My route is a clone, and the config has no kuid table, and I can't find anything labeled region. Do I need to go back to the original route and add it to that?
Okay have made some screenshots of what I did way back when and I just looked at it in 2010 and it's is doable now as it was in 2006.
First this is one of my routes
As you can see the region is right there.
Now if you search for United States using the built-in filter you'll see the following
This is the file you need to clone, once you make a clone and look in to it using CCP you'll see the following
Now you see all those cars, you can hit the two little dots and replace them with any truck that you have downloaded. This is what I did way back in 2006 and it would still be available on the DLS if one of the trucks that actually was in it was still there, but the very first truck it tries to pull from the DLS is missing, so you're not even get the region file.
But you can make your own region file from this clone with any vehicles that you want, then go back into your route after you've saved and committed your clone, and hit the button with the two little dots and change United States or whatever other region you have listed to your clone, then those trucks should run up and down your streets and roads.
Now keep in mind when you do this, if you replace all the cars with trucks all you're going to have is trucks. So you may want to use a mix if you have something other than the commercial area in your route.
