The best place to build them is situational.
Truck Action Points are non-cumulative and the the highest producing Asset is used to provide Truck Action Points.
These are basically range points and a City will have its full amount of Truck Points projected within this range. After the range is exceeded the % of Truck Points projected slowly drops to 0 upon reaching hexes at double the range or more.
Ideally you place them at the hex before you have the first reduction in TPs.
Use Preview Points to determine this hex location (see below diagram). I use stop signs to cut off all outside TP and rail points on the Preview view first. By removing TPs from other more distant truck stations, the view is limited to the closest truck station's output of TP's.
Multiple supply bases do not extend. Truck Action Point Extensions are not cumulative and constructing another Supply Base does increase the range any further. I believe they are specifically designed to sit between two truck stations.
You want to keep one supply base at equal distance between two truck stations. Just within the Truck Action point range of each Truck Station.
Ostensibly, a Supply Base III should create a perfectly efficient supply route between two Truck Station I's at 20 hexes distant.
Supply Bases make excellent locations for road junctions.
If you upgrade the truck station, the truck points increase and truck action points increase slightly. The most favorable hex will change.

* these numbers are estimates as the number of truck action points needed to move from one hex to another can be impacted by terrain modifiers.
