The biggest advantage of a gooseneck trailer over a bumper pull is its stability. Since the tongue weight of the trailer is over the truck’s rear axle instead of at the back of the frame, the potential of the trailer to sway is minimized. This increased stability also means gooseneck trailers can accommodate more weight and be larger than a bumper pull trailer. Goosenecks have more room for living quarters if you want them, as well as more room for any cargo you haul.
Gooseneck trailers also have a tighter turn radius. This lets you cut corners tighter than a bumper pull trailer and lets you maneuver the trailer in tighter spaces. This tight turn radius can be a double-edged sword, though. It takes a few tries to learn, and if you mess up you can take off the trailer’s fender, to say nothing of damaging street signs and other cars on the road.
A gooseneck trailer has limitations, though. One is its size. You won’t be able to haul one with anything less than a pickup truck, and unlike bumper pull trailers, several goosenecks are heavy enough to be classified as commercial. Gooseneck trailers also require a special hitching system, installed in the bed of a pickup truck
