Hello. This mammoth is from modern Russia, an all-terrain vehicle named IrkAZ Udagan.

It is based on Shaman ATV albeit with different headlights and details. There's an extra of foglights on the roof.

P.S. IrkAZ is a GTA-verse KamAZ, a brand that I made for some of my vehicles

Installation: put the 'R IrkAZ Udagan' into 'modloader' folder and put a line from README into gtasa_VehicleAudioSettings

Make sure you have 4 Wheel Steering Front script made by Artem.1.9.9.6 and released on libertycity.net by Dimoman for the secondary front axle to function

Info for uploaders: don't release it on liberycity.net. I'll do it by myself.
