Good method but I was doing it in different way. So as everyone knows (or not ): 1stud = 8mm. My scale is 1:19. For example let's take high dimension: 4100mm. 4100:19 = 215,8mm. 215,8 / 8 = 26,97 studs (so 27). In that calculation my MAZ measures: 184 studs long, 31 wide and 27 high.
From first scratches to final model it took me 1 year. Of course I wasn't building all the time, mainly at the weekend but not every. So it was long time...

I'm very curious too . This truck were never used to transport nuclear missiles. On the internet you can find only load which simulated rocket.
Steering isn't something genius I agree with that. But after tests where every steerable axle turns under different angle I realize that 4th axle move almost nothing. I decided to connect 3rd and 4th axle together. There are still three different angles so I think it isn't so bad
