Charge Controller/Converter issue?

It's not grounded.

If the camper is not grounded? Edit: So how would I check to make sure I'm getting the correct voltage to the plugs?

No it's not normal and potentially dangerous. What kind of RV are we talking about, a motorhome or trailer or truck camper? Is the generator built in or a portable?

If a portable check if the shore power cord has a replacement end on it. If so unplug and disassemble the plug and make sure there are no stray wires jumping from screw to screw and allowing a voltage leak.

It's a Travel Trailer (R Vision Trail Lite), portable generator, Okay I'll check the cord.

Also check to see if the problem occurs at the generator itself or is it only in the trailer? What's the rated output of the generator? Is it a 2000 W model or something smaller? Is there a make and model on it?

Are you able to plug temporarily into a household outlet and see if the readings are the same?

Here we go with "bonded", Earthed", "grounded", "floating neutral". Get some popcorn!

Don't know about the box fan at half speed.

Checked the cord and it doesn't have a replacement end on it.

When trying to chase down an electrical issue (of which I can no longer recall...) I ran into this exact same 65v gremlin a couple years back, but could never interpret it’s causation... What ever the cause, I could only write it off as a phantom meter reading as it turned out to be unrelated to the primary issue (??) at that time...Wish I could remember more details, but the 65v oddity still sticks in my memory...Though to my knowledge it hasn’t raised its ugly head since, I’m still a bit perplexed by this occurrence...Now that I read about this here (a validation), there must be some combination of sinusoidal events (half wave??) that can result in this kinda reading...

Now I have something to think about in all my new found spare time - thinking cap ON - lol!

On edit, I now believe this reading arose when running the genny (Honda 2000), but voltage at the inline killawatt meter (genny outout) remained normal at all times...

With the OP’s post, now I won’t rest - dang !!

It's a 3650 watts continuous Champion.

Since you’re reading 65v at ground to hot, and 65v from ground to neutral, it ‘may’ be indicating the effects of each half wave, but thats just a best guess...Does the box fan run at full speed when plugged into the stick built house??
