Haven't looked at the default #2 view yet, I usually start looking forward from behind and left. Which engine are you getting this on?
The cabview can be changed tho. Select the engine, "View dependencies", find the cab interior file. Edit that in Explorer, open config.txt with notepad. Change the line;
cameradefault 4
To whatever number you want to be default, depends on how many are in the list;
cameralist
{
camera0 -1.163,0.3,1.3,0,0
camera1 -1.63,0.3,1.3,0,0
camera2 1.163,0.3,1.3,0,0
camera3 1.632,0.3,1.3,0,0
}
That model is an Alco RS3 which is fairly short but has the long hood forward, so the views are aft of center. The numbers are left, aft, and up, with the minus sign in front being the opposite, right, forward, and down. Last two numbers are pitch and yaw, "3.15" is facing back, zero is facing forward.
So for camera 3, for example, I would change the last line from 1.3 to -2.0, then test in game to see if it needs to be moved further forward (add to the negative number, -2.25 for example moves it forward) or further aft (subtract toward a more positive number, -1.75 for example). Some trial and error involved, but really not that difficult.
