Dielectric grease for 30 amp plug and receptacle?

I have burned up two 30 amp plugs on my travel trailer in the last three years. Apparently, they lose connectivity, heat up, lose more connectivity, and burn themselves up. Any lubricant that would make for a better connection and eliminate this problem?

    Sounds like the connector on your trailer needs to be replaced. The contacts are no longer tight.

    Im a fan of dielectric grease but only use it on connectors that rarely get used.

    I picture the trailer connector attracting too much dirt if you used grease. I dont think its supposed to be used for lubricity. Its more the absence of oxygen and moisture. Keeps things from corroding.
