I am a first time camper owner and hope to be using this alot. It came in the mail, then immediately after we went to pick up our 22 foot camper. We only used the hitch portion of this to tow the RV home as the dealer wanted over $150 to install it. The RV tech was impressed with the quality of it though, & choked a little when I told him how much we paid for it as the ones they sell there of a different brand cost over $500. I have learned since that while this will help a little with sway of the trailer, the main funtion of it is weight distribution and eliminating the sag where the trailer hitches to your truck. There is a second device call a sway control bar that mounts to help eliminate sway. It is not as pricey around $60. I will update my review once we start using it in the spring. Note that the box is REALLY heavy.
