I think in many cases it is more about the tie rod being parallel to the lower A arm, so they swing parallel to each other. You need to talk to someone who knows about your specific vehicle, but if there is no bump steer or unusual tire wear, you are OK. The bottom line is that you don't want the length of the tie rod to change in relation to the A arm under load or during cornering as the A arm swings through its arc. If the geometry is poor, you want to compensate to try to get them more parallel (or optimal), and you want to align the vehicle while weighted with the most typical load. Obviously that may not be as important in a vehicle weighing 3 tons.

Just from what I see, it looks in one of those pictures that the tie rod and A arm are parallel. . On certain vehicles we used to bend the steering arms to adjust the swing. You should find out what other owners of your vehicle do. I don't think it is a cut and dried, one size fits all solution. If there is no ideal geometry, you want to find out what the compromise solution is, and do what works best.
