This is a high quality tow bar that contains many safety features to make towing a car behind your RV easy. When hooking up, you don’t need to be exactly right on. During disconnect you depress the two locking levers to release the pressure and allow a quick disconnect. Rubber sleeves protect the sliding steel rods so that dirt and grime do not get into the parts that need to slide easily. I would recommend using a locking device on the two connection devices rather than the rod & clip provided as the clips can fail, while driving, leaving your vehicle connected by one only strut. It happened to me, so now I use padlocks. You will need a base plate to match your vehicle and some assorted accessories.
