This is what load each rackleyXX.sii file corresponds to in the /def/cargo/ folder
Use as a reference if you wish to add or remove certain loads and job companies etc.. 
Note: The load weight in thousands of lbs = the value of "mass" in the rackleyXX.sii files multiplied by 0.22 (180k lbs is the max without changing the "gross_trailer_weight_limit")
	example: rackley5.sii "mass" value is 351.744, so 351.744*0.22=77k lbs
