me too installed 18WOS american long haul today. awesome game. but one thing which i found difficult was to find the destination to deliver the trailer. everytime we need to open the map in the notebook and check whether we are heading in the right direction or not. that is quite tiring. should have had a more detailed map on the screen itself(just like GTA VC2). that would have proved to be more useful.
and what i feel most difficult is to avoid the fine put by the cops!
thats the challenge. follows traffic rules & you will never be caught by cops.
things to note:
1) dont overspeed but dont go too slow as goods have to reach on time!
2) do not avoid weigh stations.
3) signals can be broken!
4) dont crash as you get penalty on goods & also you spend on repairs.
5) avoid too many mods in the initial stages where you get basic trucks. save that money & buy better trucks & then mod it completely.
