I have a Drotto on a 175 and will never own another trailer without one. Back in until the back end floats, get in the boat and pull the rope to release. Pull back on the trailer and it latches.No leaning over the bow to hook up. I let my tailgate down and launching step over in the back of my truck and just step over on the bow of the boat and loading let it latch and step over onto the tailgate and never have to climb on the tongue or get my feet wet. Easy for a 70 year old that fishes by himself all the time.
