A/C tripping the breaker

Tough question here...

Our 3 year old Coleman Mach air conditioner started tripping the breaker this week. It started Saturday. Breaker tripped. Reset, started and tripped again. This went on about 4 times. Shut it off, let everything "settle," cleaned the rooftop unit (some bugs and stuff in it, not overly bad) and reset. Ran for a day and a half. Wifey came back and breaker had again tripped.

We are on a seasonal site, it's been in the upper 80's lately and everyone is running their A/C's. Mind you, it's not the first time it's been this hot.

What could be tripping the breaker? Possible "spike" in the line doing this? Something I'm missing? No other breakers are being tripped, just the A/C.

Anything I can try before calling in a technician?

Thanks in advance!

Bob

also, do you have a line filter on your power coming into the trailer?

No line filter and I was wondering about that

My neighbor went up and cleaned the HECK out of it. Said everything is spinning fine, fired it up and didn't hear any bearing issues and said it sounded fine.

Yes, the breaker was hot to the touch (according to wife). I haven't been able to get down there to look myself but my neighbor is very tech savy and even he can't figure out what it is.
