On the topic of the garbage truck, BeamNG did previously make a garbage truck for a training simulator for Waste Management https://beamng.tech/references/beamng-sigma-integrale-waste-management/
That was all the back in 2021 though, I feel like we would have gotten it by now if they were going to add one
After looking at the images I am 90% sure its in BeamNG. The only thing I am suspicious about is that it was a while ago, though this could be because they had to rebuild it to be lore freindly. --- Post updated --- They need time to make it lore freindly, meaning they likly had to redo it from the ground up. --- Post updated --- I am pretty sure that all those complex mechanisms are the trash compacter (Going with my garbage truck theory)
My bet is on a rotator crane upfit for the T-series. The big bundle of torsionbars on the ground to the left are the sling, the "hook" of torsionbars at the back are the sling thing, the 3 horizontal sets of slidenodes are telescoping boom and rams, and the trapezoidal thing at the front is the lift pivot point. As for "we can't see the chassis" they could easily exclude the chassis slidenodes by putting the upfit's straight in the chassis slot. even if the jbeam isn't stable, they could have just taken the picture with the physics paused.
Again, too completex for a trailer, and doesn't even have legs Its not a vehicle, it's 20 meters long and doesn't have a framed or suspension On my perspective picture, you can see that the dense thing at the rear constructed mainly from slidenodes and maybe torsionbars Is straight, so I'm pretty sure its an ramp that extends or something. (Solid structure) I Don't think they would make that effort just to confuse us, also it's at least 65,6167979003 feet long
The teaser came out a little late, it's very likely that the update will be small, but we'll see in the next teasers.
