I was driving a Ford E 250,for some owners.I was offered a 2770 pound load from western Pa,in the AM to the west subburbs of Chicago,DELIVER AT 0600,THE NEXT DAY.The distance is not far.I turned the load down.In my eyes I was looking out for the owners van,hauling such a load,being a SAFETY issue in my eyes...The weight capacity of the van.Now because the owners of an unmentioned expedite company,didn't want to place their van in the .70 rates,decided to run their 3/4 ton van,as a 1 ton van. Hmm.I did however,contact my fleet coordinator about this matter.And he contacted the owner.The owner is still having a cow over the fact,why I turned the load down.I wonder what DOT and the expedite company president would say about this ? If it was my van,I still wouldn't take it.Not that it would put much stress on the engine,would it? But the load had to sit all day,and overnight,putting stress on the rear axle.
