This one was my first ever MOC created about 4 years ago. It has evolved over time with the availability of parts, inspiration from fellow builders, and strengthened ability using LDD tools.
Some things to note:
Trailer hitch points in the same location (IE: ability to change and swap trailers).
LED lights on the back of cab.
1 tile clearance underneath a flat floor.
4X spare wheels under the last trailer and storage under the front.
Trailer doors operational with smooth floors inside.
Refrigeration units recessed.
Air / power lines connecting the trailer units.
Trailer units are the same overall length.
Vehicle and trailers interchange with all of my 6-wide trucks.
Thanks for taking the time to check it out. Looking forward to showing everyone more builds. Cheers :)
