A truck whether civilian or military is designed for a duty (light, medium, heavy, super heavy etc) and dimension, weight carrying, terrain etc.

Most military vehicles are designed for a task (tank recovery, portable field hospital etc )potential attacks etc. The government (funded by the taxpayer) is paying the fuel bill so the frame and add ons can be heavy to cope with rough roads if there are any and 24hour/ 7 day vehicle use.
Rheinmetall MAN Military Vehicles - Wikipedia
Military trucks tend to have government/ military - repair and maintenance costs. Engine set up to run on military fuels etc

For normal civilian road trucks it is best to look for the dimensions/ metal quality of the frame steel and design of the frame etc. The road truck company prefers to carry customer load rather than truck chassis weight - frame design light as possible while keeping very strong.
e.g Scania if you want to get technical. (Probably Volvo too - in Finland trucks are running at 185 000lbs now and going heavier)

To extend a Scania truck - cut truck and add in sections of steel from donor scania truck chassis. Add additional braces as per local truck regulations.

If you think the road going scania are too light then the belgium and german oilfield trucks. Offroad and the oil company is paying to carry the load.

Its hard to say what alloy or temper they are. Ive torched apart two M939s and welded back together a mack RD double frame. The mack sure was a lot of metal but it was busted clean through in 4 different spots and had a heck of a swayback. Plus the walking beam tower was tearing out.

Ive not ever seen a broken 5ton chassis component but then ive never seen a real engine and trans in them, nor ever seen one with a high side dump bed and 400k miles of offroad on it either. If offroaded hard they tend to pop the rear axle dogbones out of the rubber so guys weld restraint straps over them. I mean rockcrawling, not just haul road offroad.

The allison convertors are known to stay locked up in 2nd during a panic stop which stalls them and kills brakes/steering. Plus they have wedge brake backing plates, not S cams, which stink. There is one obsolete meritor axle (i think its meritor) that had bolt on conversion backing plates to S cams but theyre hens teeth, i have a buddy who looks all over the US for them.
