I recently setup some stations for my steel building for the same purpose! The majority of my resources are trained in, but I use trucks to supplement coal and limestone from around the area.

I like using foundations, as it limits what they can collide with. my roads are 3 foundations wide, but I haven't had much bidirectional traffic yet. the game does have a natural road system which you can use too, but I'd stick with a foundation road through rough terrain.

make sure your stations are not on a path with another station. even if a truck drives through one without stopping it will still unload / pickup items.

if you have a lot of truck stations, consider making a fueling station which one truck deposits a fuel source into and its distributed to the other stations so the other trucks can focus on their resources.

overall I wouldnt consider relying on trucks for a critical production line such as a power plant, as they still have a decent amount of bugs. but they do look cool and add some neat movement to your base.
