That is a killer idea. Just for clarification, the product used is a ladder stabilizer and you cut it in half so there would be one for each side of the trailer?
Yes, the cheaper ladder stabilizer at HD $ 25 not the heavy duty one, then I just bought 2 pieces of precut PVC , 2 Ubolts and thats all, It almost fit perfect without cutting. I cant take credit, I found the info here doing a search...
