This is one of my latest mods. I wanted a way to get rid of the bouncing that you would feel when some one would walk through the trailer. I had some stabilizer jacks that came on the trailer but were replace during another mod I was doing at the time. This turned out working great and I was very happy with it. Well worth the time.
Drilled a hole through the 2x2 box tubing with a hole saw bit.
Made up the bracket, sand blasted and painted as much as possible to make it easier under the trailer.
I welded a piece of black wall pipe in the holes I drilled to act as a guide for the wrench and to reinforce the hole.
