Replace/Insert

[Nudie]

Replace the Roadtrain with the Tanker + Wagon because it's faster then the Roadtrain and better to turn with.
Put in the firetruck because it's a good vehicle to drive and it's funny to crash with

No further changes with vehicles will take place until Sanandreas Multiplayer 0.2.5 is released.

[Sander]

Amen.
