I found a helpfull advise in the german TSM forum to the frequently asked question : What is the loadorder ? - Where should I load this mod ?
The advise was in german:
In english it's :
Map (below in the load manager)
Weather and Grafic
And my load orders are build with this tips in mind and so I've got no load order problems.
Some authors are given in there release post a load order (e.g. Drive Safely) and these orders are tested from them and nearly the same as above.
