Why not kill two birds with one stone? Install a pair of guide poles on the
trailer. They will help you guide the boat onto the trailer and provide a
taller point on the empty trailer that you might be able to see over the
tailgate.

Also, you can mount the taillight on top so they are more visible to other
drivers, and do not get submerged when you launch.

Unfortunately, they do not fit my particular trailer configuration. To
help back down my unloaded trailer, I bought a 3M Vangard fresnel lens,
which sticks by static cling to the back window of my Suburban. You can
buy them in places that sell RV equipment. I don't think they will help in
this person's application, because sticking one on the back window of a
pickup wouldn't really improve the field of view.
