My "workaround", which seems acceptable on Trucking servers, when working as a Trucker or maybe Courier, is to stay within a limited area of the world. For example, to drive from Bayside to LS along one route, let's say the LV motorway, and return via that particular route back to Tierra Robada, without touching Flint County. I have played for several hours without a crash this way, then I can re-log and service a different chain of cargo depots. It is possible to travel greater distances in the custom (simpler) section of TruckMania's world map before a crash is induced. (i.e. the crash has nothing to do with time elapsed, as I first assumed, but instead the "amount" of world loaded.)

This Post claims that version 344.75 of the driver works, without giving an explanation why that would be. (I'll try this when I have a strong reason to perform a low level reinstallation of the system.)
