the panel in the trailer gets hot and the main breaker on the service panel outside trips but none of the breakers in the trailer trip

Is there a question in there somewhere?

When you say "service panel outside" do you mean the main panel for the house/building that you are feeding from? Or does the RV have a disconnect outside with a main breaker?

Sounds like loose connections somewhere but without more info it's hard to tell.
Give us more info such as what loads are on and the general setup you have.

That's if you were asking a question to start with!

Loose connections heating sub panel would not trip the breaker in the main.
Either the total current through the breakers in the sub is enough to trip the main or there is current in the sub that is not going out the breakers.
Lots more info needed, but a thermograph and amp clamp readings will probably help.

By "main" I was referring to the breaker that was feeding the power to the RV panel.
Like maybe a 50A breaker in the service panel of a house/building.
I do agree that more info is needed.

the rv is plugged into an outlet at the lot panel each lot has a service I've not been there the rv has a panel inside

30A service.

50A panel drawing 40A.

Happens all the time with RV's & RV parks.

Though probably not too likely to make any difference on the heating up of the panel in the RV, which OP said was happening, the fact someone may be using a "cheater" on the supply cord to plug into a lower capacity outlet is a good possible reason the breaker in the supply equipment is tripping.

More details on this inside panel will give us clues on the heat produced there. Is this a simple distribution that directly utilizes incoming power or does it have converter/inverter for battery backup as part of the assembly? Those can be heat producing under normal conditions.
