300 miles one way is an ~11 hour day if he is near you. 3400 is a little steep, I would think more like 2400.
I'd surrender my right arm if it can be done in 11 hours.300 miles 1 way is 600 miles round trip. perhaps we are saying different things but I can't drive commercial and load unload in less than 11 hours.
He seems madLOL heated?
I look at my readout on my van, it gives average speed. I live 50 miles from the closest interstate. I drive secondary roads & the biggest highways I'm likely to drive are 55 MPH speed limit. Still, the stop & go of each intersection, I'm averaging 38 MPH. Perhaps you are correct, on interstate you might average 60 MPH, gotta stop to pee. Unlikely, each end of 300 miles are interstate, & you gotta load & unload.I guess you don't haul equipment. this machine is just over 20,000 lbs. Light load. I haul equipment all over florida, heavy equipment. 40,000, 45,000 lb machines. If they are secured properly you can do the speed limit, over if it's safe to do so. There is absolutely NO reason why it should take more then 5 hours to run 300 miles , all of it on Interstate highway, averaging 60 mph. YOU my friend, just lost your right arm!
