Geez. There are so many possibilities that could be causing my problem !! LOL
My question is that if I have a short btwn a ground and neutral then why does everything work ok from the genny? Wouldn't everything run through the breaker box whether connected to shore power or the genny and therefore the short would still exist? Im going to buy all new adapters and extension cord and try that. they all checked out fine with the ohm meter but maybe under load there is a problem??? There definitely is a problem though because the last time I tried plugging into my garage the cord plug and wall receptacle arched pretty significantly.

The generator does not have a GFI. A GFI has a circuit that detects ground/neutral shorts and immediately trips. If the cord is the problem than it will trip the GFI without the RV being plugged in. Unplug your reefer and disconnect your electric water heater element if you have one. The other likely cause is water in the outside receptacle. If these are not the cause then you have to take the neutrals loose until you find the problem.

Sounds to me like you have something bad in all the adapters. Have you tried plugging in all the adapters without plugging in the 50 amp?

ive plugged the adpaters into each other and then into my garage via a 12 gauge extension cord (without plugging in the 50 amp cord from the trailer) and the gfi circuit in the garage holds. As soon as I plug in the trailer's 50-amp cord the garage gfi goes POP!

At the FamCamp here on base we used to run into this problem when plugging a GFCI protected unit into a GFCI outlet. I liked to call it dueling GFCIs. Have you tried plugging into a non GFCI protected outlet in your house?

Yes. Into a 20-amp NON-GFI outlet in the laundry room. as soon as I plugged in, the breaker at the panel popped.

That pretty much changes the ball game as this is not a GFI problem. Your cords could very well be the problem, replace the extension cord first and then start with the adapters.

You have a short in one of your extension cords. If you broke off the prong on the 3 prong cord that could cause problems.

First, GFCI's should not trip on overload,, They trip on imbalance.. The 20 amp breaker trips on overload..
So I'd guess you have a hot-ground short
Cords are a good starting point and you can quickly check them by either disconnecting the cord from the rig and plugging just it in,, Or by tripping the main breaker in teh rig by yourself.
After that it gets interesting
The generator does not have a seperate ground
It does not have ANY ground
Nothin adds excitment like something that is none of your business

I bought another new adapter and plugged my trailers 50 amp cord into the new 50/30 adapter. then i plugged the adapter into a brand new 30 amp extension cord. I plugged the 30 amp extension cord into a brand new 30/15 adapter. i plugged the 30/15 adapter straight into my garage outlet and................POP!
Could it be my house's electrical??? I plug the service cord back into the gen set adapter and everything in the trailer works fine.
I also cheked every outlet in thet railer with a ground fault detector an all outlets are working properly.
I am stumped. The garage gfi pops even when the trailers breakers are turned off. What the heck!!!
The ground from the a/c distribution box is mounted on the frame and looks just fine.
