Question about fuel level on trucks

Whenever I place certain trucks, such as the Maz onto a custom map, it's fuel level is considerably less than 100% regardless of the fuel setting in the editor or proximity to a garage. Is there a way to have these trucks start with full tanks?

What trucks have you tried? I can test this on my map after I have eaten.

@bob97470, From my experience, I believe they are only filled with 200 ? and didn't see anywhere to change it. It's been like that for a while now after an update to ST long ago.
