So, I think I need to keep the trailer plugged in so I can back up. Unless the advice would be that given the trailer clearly should be urged away from the truck once I'm at the ramp so that the brakes shouldn't come on (i.e., heading down away from the truck), it would be ok at that point to unplug the trailer??
Thoughts?

Well the advice to unplug the trailer so the hot lights won't pop if exposed to cold water is sound but in your case perhaps you have no real choice. Most of the time the light bulb is (should be) sealed off from the water.
If it isn't
then you run the chance that the bulb will pop. In your case I say bring spare bulbs and a screwdriver and let them pop. Leaky housings should be replaced anyway (when you get a chance) and I'd replace them with LED taillights, which you don't have to unplug.
