the same products used to maintain tank drain valves work great on hose connectors...
aerosal spray or grease versions.
these are commonly used as O ring lubricants in drinking water systems.

web search '
food grade silicone' for a lot of vendors.
the sprays will collect less grit than the grease,
but a thin film of grease will last much longer.
plumber's grease from gunk is a common brand available.
________
the problem is typically galvanic corrosion mixed with mineral deposits.
switching all the connectors to brass or steel or nylon helps too,
but 1 can of spray and 1 tiny tub of grease will last for years.
the spray is used with window seals, door gaskets and lots of other bits around the trailer.
