Hi, recently we purchased a 12' trailer with a dovetail end, thinking this would make it easier for loading equipment. Well, anyway.. that's a different problem.. Current problem is the back of the trailer only clears a smooth, level, surface by about 6"... if that much. We have heard a rumor that there is some type of solid steel wheel that can be mounted under the back of the trailer to keep the angle iron from dragging over high spots. We've already brought back a few nice size chunks of roadbase (and large rocks) from having to drive over roads that are being redone and need to find a way to increase the distance from the trailer to the pavement on the trailer. Are there maybe spacers that could be installed in the springs to raise the whole trailer? Any help, sooner the better, would be appreciated.
