Google 50 amp RV cord. They are different than what you have. I would guess that some previous owner made some changes, perhaps from RV 30A to 50A.
A google search for "50 amp cord" shows various styles. The one most common to folks is the
50 amp extension cord which has a standard 50amp male end and a standard 50amp female end.
On most RVs, the shore power cord is wired directly into the RV converter and you simply push the cord into an opening on the RV side to store it. If you need more length, you use this extenstion cord.
However, some RVs come with a marine-style detachable shore power cord. When the RV is to be hooked up to shore power, the power cord is plugged into a
Power inlet that is wired directly into the RV converter. This inlet has a different plug pattern than the standard 50amp pedestal. This pattern allows the plug to be twisted slightly when plugged in so that it does not fall loose. When the RV is not hooked up to shore power, the cord is detached from both the pedestal and the RV and stored.
That the RV is set up to have two ACs suggests it has always been 50amps. And the label next to the power inlet suggests the power inlet was installed by the manufacturer or dealer (a do it yourself job wouldn't add the label and the label wouldn't be necessary for a standard directly wired power cord).
This RV is simply set up with a marine-style 50amp detachable power cord.
The power cord provided to the OP is a 50amp marine-style female end to a 30amp standard male end.
If the OP wants full 50amp power, they will need a 50amp marine-style female end to a 50amp standard male end cord like
this.
