I have seen trailer frames with stabilizers attached on diagonal steel in frame corners. The pictures that came with my jacks show them along the left and right frame pieces. Not sure I am going to describe this clearly but I have noticed that the flat plate is just a little wider than the upright so that when it is in travel position, it would rub against anything that its at the same level as the attach point. If it is attached along the outside frame pieces, it would rub the paint allowing rust to set in. Does anyone have any thought on what should be considered when choosing an attach point?
Thanks
