Okay guys, what went wrong here?
Assuming the weight density of gasoline is similar to water..
The tank, filled with sand and dirt from the area, along with extensive amount of metal added to the tank..
Ending up at least 37% over its capacity and would have collapsed the suspension.
At the very least it would look wrong driving down the highway.
Very slowly.
* Fact check: yes, it's probably true they would just fill it up halfway. Go with me here. I want to submit this to Mythbusters.

Bulk density of dry soil can be a good bit less depending on organic composition. That being said, yeah, mostly sand despite a portion of much lighter powdered clay, so closer to 1600 kg/m^3 than 1000 kg/m^3 (which sufficiently organic soil can weigh less than).
At an eyeballing, I don't think the steel added to the trailer is more than about a half ton. That seems like a lot, but is less than a half a cubic meter's worth, so is inconsequential in the long run. The cab wouldn't be bothered by the cowcatcher weight, particularly - it suffers worse front axle loading going downhill with a full load.
Taking all this into account, it all comes down to the amount of fill and the safety factor the truck is designed with. Given that it's a general liquids truck capable of carrying things just slightly heavier than water, if the truck operates structurally with a safety factor of 2+ (not uncommon for moving applications) it's well in the clear, punishment to the springs notwithstanding. If the safety factor's closer to the static load 1.4, it's probably overweight at 100% fill, but not murderously so.

Yes, thank you for indulging in my random thought experiment. Next time, we deconstruct the the physics of the Knight 2000 Turbo Boost :)
