Golf carts that are battery powered are quite heavy. Although most 1/2t long bed trucks should be able fit them, not all will have sufficient payload. The ramps you choose should have a suitable payload capacity to support the golf cart. You should not load the cart on the tailgate due to the weight and may want to look into receiver mounted extensions that will help support your ramps while loading and unloading. A bed or cart mounted winch may be safer for loading and unloading than trying to drive up and down the ramps.
