Abstract: A trailer with wheels located near its rearward end and a connecting arm extending from a mid-region of the forward end of the trailer. The connecting arm includes a gooseneck with a ball receptacle to connect with a ball protruding upwardly from the truck bed. A shroud is connected to the forward end of the trailer beneath the connecting arm and a powered hydraulic cylinder is carried inside the shroud and includes a rod extending downwardly to raise and lower the front of the trailer. A stabilizer arm terminating in a foot portion is carried by the shroud to extend downwardly and co-extensively with the rod to protect the hydraulic cylinder and rod from loading other than by the weight of the trailer and its load.
