I assume the corrected ground may now be masking the ground fault issue.
Try plugging into a GFCI protected outlet.
And no mention of using an outlet tester... so polarity could still be an issue.
When an RV Ground/Chassis is allowed to float (ie: open ground), the capacitance between HOT to GROUND and GROUND to NEUTRAL will cause the floating Chassis to assume a voltage level < 120/2 = 60 VAC above Earth. The resulting current leak, which is normal, may or may not be enough to trip a GFCI.
YUP.
Not to mention the trailer its' self HAS GFCIs through out..
GFCIs CAN operate WITH OR WITHOUT a "ground" since they are measuring the HOT and NEUTRAL current. A GFCI will only interrupt if it detects MORE current flowing on the HOT than on the NEUTRAL (IE HOT AND NEUTRAL current MUST be the same)..
The problem the OP had was most likely a bad ground connection within the extension cord. This could be a broken ground wire anywhere within the cord or at one of the ends or possibly a bad ground connection at the female socket end (worn out ground socket which is common with heavily used extension cords)..
Basically they had the HOT SKIN syndrome.
