A trailer stabilizing system comprising:
- a repositionable semi-trailer stabilizer including:
- a first support mounted to a first repositionable jack and a second repositionable jack, the first support also mounted to a first wheel and a second wheel;
- a contact plate extending over and in between the first and second repositionable jacks, the contact plate mounted to the first and second repositionable jacks, the contact plate including an upper surface configured to contact an underside of a semi-trailer;
- a semi-trailer stop configured to engage, in a first direction, a vertical surface of the semi-trailer to retard horizontal repositioning of the trailer stabilizer in the first direction post engagement;
- a drive shaft extending between and operatively engaging the first and second repositionable jacks;
- a camera;
- and,
- a display configured to be communicatively coupled to the camera and display images based upon signals from the camera.

A method of stabilizing a parked semi-trailer, the method comprising:
- manually repositioning a trailer stabilizer, that includes a pair of telescopic jacks, at least partially underneath the parked semi-trailer in front of landing gear of the parked semi-trailer, by rolling the trailer stabilizer so that the stabilizer passes under a forward edge of the parked semi-trailer and is generally laterally centered with respect to the parked semi-trailer, so that a portion of a handle of the trailer stabilizer is beyond a footprint of the parked semi-trailer;
- manually cranking the handle of the trailer stabilizer to reposition a drive shaft operatively engaging the pair of telescopic jacks to lengthen a dominant dimension thereof, causing the pair of telescopic jacks to wedge the trailer stabilizer between an underside of the parked semi-trailer and the ground so that the trailer stabilizer and the landing gear share weight bearing responsibility for the forward portion of the parked semi-trailer, and causing wheels of the trailer stabilizer to be lifted off the ground.
