So, this massive 49 ton beast is powered by an 800 horsepower 14 liter V12 Detroit Diesel, the 12V-71N, or at least the closest I could get since I can't figure out how others have made 2-stroke engines, perhaps that's even a custom version or mod of the program, I can't find it on the Discord but I'm probably just not looking far enough back for it. Anyways, this is a giant 8x8 military truck, and while normally its only just 19 tons, this one has 30 extra tons of equipment attached to it making it 49 tons. I ballparked the tyre height and calculated the gear ratios to make it have a theoretical 25 speed gearbox, and I added an extra 26th gear before 1st (now 2nd through 26th in the GUI) to simulate launching from a low-range gearbox in 1st, one with a 1.75-to-1 gear reduction overall for those extra steep inclines. It maxes out at around 2 or 3 mph in low-range first gear, or nearly 5 mph in high-range 1st gear. I'll actually upload the Excel spreadsheet too in case anyone wants to calculate the ratios including a final drive "launch gear" in front of it all. It has convenient bar graphs to visualize the gear ratios as if its showing the wheel torque, with color gradients too for extra visual help showing what could be considered driveline stress as speed goes up with resistance to acceleration, and the other color gradient is the speed based on tyre radius and gear ratios entered at the top of the spreadsheet.
The Catalog has it here:

And both the engine and the gear ratio helper spreadsheet I made can be found here, the engine is called ultradiesel_v12:
