I managed to find two decent pictures of the Thibault with the outriggers down, they might be useful if you do decide to implement the rigs in the future. (I did find some photos of the Metro-Dade rig along with some other unique apparatus.)
I know this was mentioned in the past, is there any plans to implement canopy variants for the open top rigs? I do have some pictures if anything is needed.
I do also have some suggestions for retro semis if you need anymore. Some GM rigs would be good additions, like the GMC General and 1972 Chevy C60. And some cabover trucks like the Pete 352 and White Road Commander.
