Each combination of tow vehicle, hitch, trailer, payload, speed, grade, road surface, wind conditions, .... can have slightly different behavior.
U-Haul, IIRC, also specificies no more than 50 or 55Mph on their trailers.
The weight is well within the capability of the vehicle. Take it slow and increase speed until you hit a comfortable speed unless things start feeling "weird". If so, back off at least 5Mph and go from there. I, personally, wouldn't go faster than 60Mph with that configuration. There's just too much that can go wrong too quickly with towing to try to shave a few minutes off travel time.
To rephrase @SkipW
, it's better to arrive at your destination than at the hospital.
