I saw this YouTube video where there was two types of fire trucks installed. The guy had the ELS MTL Engine installed and the Seagrave Marauder II Engine installed, all under the fire truck section. When he steps into the fire trucks, the bottom right says "Fire Truck", indicating that the player has entered the Fire Truck model. I figured the two fire truck models were installed to replace the original fire truck because the water cannon on top was moving, just like the original model. Does anyone know how he did this. If so, how is it done. I don't know if I worded it correctly above. I tried to go into much detail as I can.

I have 3 or 4 fire units in my game. I have the Ambulance, Firetruck, pstockade and nstockade usually. They all say firetruck because I use the firetruk handling line when I edit my vehicles.ide.
