Planning the drive

A loaded box truck is slower than a car on hills and safest at moderate speeds, and most drivers find 450 miles a comfortable day. That makes Seattle, WA to Dallas, TX a 5-day drive, so budget for hotel nights and meals on top of fuel. The rental itself and any per-mile fees are charged separately from fuel.
