How strong are they? Are they only for stablizing, or can they take the full weight of the trailer?

They look like regular tongue jacks, so should be able to take the full weight...
BUT they are mounted on the bumper...not the frame, and the bumper should NEVER be used to lift the trailer....so looks like used for stablizing only.
