We have the Hensley Trailer Saver BD3 and consider it one of the best investments, along with the MorRyde suspension, that we've made to protect and preserve our fifth wheel that we purchased new. We've never experienced any bucking, chucking, jerking, whatever else can happen with other hitches. I forget the trailer is behind us as our ride is exactly the same towing or not -- very comfortable! I have a bad back and I would know if it wasn't!
Between the hitch and the suspension, we have a very smooth ride and we can leave things sitting out in the trailer and they don't move. I've accidentally left the dog's water bowl full of water sitting on the floor and over a 100 miles later discovered not a drop was spilled.
Neither the Hensley nor the MorRyde were cheap but we consider them both to be excellent investments. Worth every penny!
