Parkit 360 Force 10k Electric Trailer Dolly. We bought this last October to use with out bumper pull trailer. We used once to put the trailer on the side of the garage. Works like a dream making moviing your trailer around and into tight spaces with no effort! Then we decided to sell out trailer this summer so used the dolly once again to pull the trailer forward. No one should own a bumper pull trailer without havng this dolly! Handles trailer weight up to 10,000 pounds. We paid $2,700 plus tax. We are not going to get another trailer so don't have a use for this Gem. Check out features at parkit360.com
