There are five models:

-Hauler;
-Hauler XL;
-Hauler XL - GunGirl (By BoB_MARLI(RUS))
-Hauler-Packer;
And an early version of the Hauler (WARNING May contain some bugs. Put him just for fun):

-All models have extras in the form of visor above a windscreen. On the Hauler and Hauler-beta there is extra of a wind deflector;
-All models have their own shadow, LODs and cols;
-Use only original texture from GTA SA;
-Rear mounted double wheels (should work fine with SilentPatch);
-Two-tone body;
-Pretty good looks in the game.
