I helped out a farmer this fall bring in his crops and had the opportunity to use his truck that had this DMI hitch that made looking up anhydrous tanks real easy. I sure would like to find one use for my for Ford truck to pull my 16' trailer. What it dose is extent out 6 or 8" and swings left and right 6 or 8 inches each way so when backing up the the trailer you don't have to be but close. Then pull 2 pins and slide out the hitch to position it under the trailer and lower it down. Once the ball is coupled just back up and the hitch unit will slide back into place and lock in place. a simple and fast way to attach the trailer. Anyone using something like this?
