I purchased a Pro Series PS49901 for our Ar-One 15RB for $255 and love it. It is inexpensive, it works good and the only "draw back" is you must disconnect the sway control when backing up. If you are backing up in a relatively straight line in can be left connected but it must be disconnected if you have to turn. If you do not disconnect it when backing up the sway control may bottom out and bend or break or it will come apart. To disconnect you only have to pull one hair pin and lay it on the tongue. They work great and are inexpensive compared to Reese, EZ-Lift, blue Ox, etc. The Pro Series is the Reese economy line and the fit, finish and workmanship is excellent.
