What has me questioning this is the fact of this being a new outdoor heavy duty cord... Both ends are shielded from the weather so how could wster be shorting to ground??
Shielded from weather does not mean waterproof. All it takes is a small amount of leakage for a GFCI to trip and a bit of condensation can be enough to cause leakage. It could also be related to moisture where the power goes into RV. Remember the idea is for the GFCI to trip well before the risk of electrocution due to a ground fault.
Not to hijack the thread but you say you have a freezer on a GFCI. This is generally not recommended as inductive loads such as freezers and refrigerators can cause false trips of GFCI. I would suggest you have a single outlet without GFCI installed for you freezer. This is allowed by code in most places as long as it is dedicated to the freezer and clearly marked.
