280.000 pounds seem pretty mad. Pretty sure we'd need more rubber on the road to haul that much! xD ...everyone wants 4 axle trucks or more, here's a reason for it! xD Not sure its very realistic as it stands now!
A quick google, a trailer hauling that kind of load would need atleast another 2 axles if not more in the USA.. xD its 127 tonnes!
If I read it correctly, according to a 2005 spec plate from one of these it can take 11500 pounds front and rear? Or about 22 Tonnes

so we are 107 tonnes overweight! xD (On the larg tri axle) ..I think xD
