How much do these truck parts weigh?

Hello all,

I am a graduate student studying mechanical engineering and I'm working on a tanker truck model. Here is an example of someone else's model, so you can get an idea of what I want to do:



In order for the dynamics of the truck to be accurate, I need to know how much the various parts weigh, but I haven't had much luck finding them online. I plan to model a Freightliner M2 106 specifically (https://www.freightlinertrucks.com/Trucks/Models/M2106/), but weights for any comparable tanker truck would at least help me get ballpark figures.

- Cab (regular day cab)
- Frame
- Front steer axle
- Rear drive axle (tandem)
- Wheel (I found someone saying 125lbs online, which sounds plausible)

Apologies if any terminology is incorrect or doesn't make sense; I'm not well versed in tanker trucks yet. Any information you can give would be much appreciated!

 

I figured that would probably be the case, but couldn't hurt to try! Who knows, maybe someone has access to a document with technical specs.

I have already received useful info in another thread I made so I'm sure I will be back to tap into everyone's expertise!
