I have a 5'x8' utility trailer. My golf cart barely fits lengthwise. I had to remove the aftermarket rear seat, which I'm not using anyway.
There's NO PROBLEM towing a utility trailer at highway speeds! The size of the wheels, and wheel bearings, aren't much different than some of the smaller automobiles. The wheel hubs never get more than warm to the touch (normal).
The furthest single trip I towed a loaded trailer was 7500 miles. I repacked the wheel bearings myself (old school method), and kept the tires properly inflated. I do bring a spare, but have never needed one in the 30+ years of hauling utility trailers. Different story with my travel trailer though.

I did put a hitch on the back of the golf cart, allowing me to move the trailer at the campground if necessary.
Check the torque on the golf cart roof, and any accessories. I'd probably remove the windshield if I still had one. Mine was only held in place with rubber blocks.
