Assuming that there is only one driver, 750 miles is 12.5hrs and 1000 miles is 16.6hrs at 60mph average. Both of those are above the 11 of 24hrs that a commercial truck driver is permitted to be on the road in the US.

I try to stay under 8hrs per day for long trips with around 7 being my target average.
