If you can't safely tow at the speed limit you are obstructing traffic
and unsafe. A good pickup truck and a properly set up trailer should
be able to tow at 70 mph without any trace of instability. Speaking
from experience, if the vehicle, tongue weight and tire pressure are not
correct you will be lucky to get over 55.

However, some states set a maximum towing speed that is sometimes below the posted limit. 55 max
isn't uncommon.
