I trailer my boat alone a lot of the time. Another thing I found useful for launching and loading in the dark or low light; Take note on a good bright sunny day of how deep your trailer needs to be for optimum launching and loading. Mark your fenders at the waterline, then apply reflective tape at the marked lines on your fenders. Now when you back down, the tail lights on your truck will illuminate the reflective tape. If the tape disappears below the waterline, you know you're too deep. You'll also know if you're not backed down enough.
