that's a neat idea with the lights on the guides. i might try that. i have a ford explorer. when unstrapping and preparing the boat to launch, i open the back hatch and keep it open. i use the mirrors a little bit, but mostly turn my head to the back as i can see the entire boat and trailer through the open hatch. my kid is usually back there holding the rope for when the boat floats off the trailer, so i have to pay attention to him as well. when by myself, i back it about half way in, get out and push it the rest of the way. when pulling the boat out, i also leave the hatch open, but i use the mirrors as i'm facing forward to drive up the ramp. leaving the hatch open allows me to see the whole boat and trailer even when using the mirrors.
