Judging by people's reactions (or rather, the lack thereof), it seems only me and like 2 other guys in Australia like 8-wide vehicles, but I'll keep making them anyway.
Here's not just a Super Duty, but Ultra Duty truck! I wanted to make more big 6x6 vehicles (like wreckers) but didn't want to keep buying bricks for all of them. So, the next best thing was to make this base truck and only build different modules for the bed. I kept the construction simple to maximize customizability.
-Going to add fender flares, I just need some cheese slopes to stick on there
-Can easily add extra axles, extend cab or bed, etc.
-Can easily swap out modules to put on the bed
-Can easily attach other things to bumpers by removing a few pieces
-Roomy engine compartment
-The LDD file contains the 6X6 and 4x4 chassis, it's up to you to add an interior and engine.
