I've extended the tongue on a few trailers that I needed more turning length, ie dually flatbeds where the typical 36-42" trailer body to ball spacing does not work or the trailer hits the corners of the 8' wide flatbed. So extending the tongue another 12-18" works well in this situation. Even an extension like the torklift will not allow one to 90 degree jack knife the trailer on a wider truck.
Either may work depending upon multiple issues you have vs what I have or someone else may have. Choose poison carefully.
