As I was checking the tire pressures this morning prior to leaving the campground, I felt a shock when I touched the wheel. Being male, I had to do it again, and sure enough, electricity. At the time, I was still plugged into shore power.
We left the CG and have pulled into our next CG for a few days. I plugged in and haven't been able to shock myself yet.
For those who know, might this have been an issue with the pedestal at the last CG, or is this something I'm carrying around with me?

You need an outlet tester. You are checking for reverse polarity and/or bad ground.

Likely a problem with the last pedestal. But, do get an outlet tester. Cheap and easy to test for such problems.

My installation instructions for my Freedom inverter says that a connection between ground and neutral at the wrong place in the RV & inverter wiring can cause a potential between the RV and the earth. But I don't remember the details, and the manual is in the RV.

Standard inverter language which means (unlike at your home residence) that inside your Main service panel, the neutral bar (white wires) and the bare copper wire ground bar have no continuity (e.g. are not connected or 'bonded'). This is because the required bonding occurs elsewhere via the park pedestal. More than one bond would likely lead to circular current paths thus trip your GFI's.

Was it under a slide? My TT must pinch a wire going to one of the 12v lights in the slide because more often than not I blow the fuse going to the interior slide lights when opening/closing the slide. I've also felt a mild shock on a few occasions.

There should be no shocky even with a bad ground. The purpose of the safety/case/chassis ground is to get rid of the problem before it hurts you. If you get shocked there is a problem and needs to be looked into before it gets worse. JMHO.

And therein lies the problem. He didn't HAVE a "safety/case/chassis ground." An open ground will give the OP exactly the symptoms he experienced. The mild shock was the result of the RV being inductively charged by the internal wiring, with no ground connection to bleed it off. The next park had no such issue, hence the symptoms disappearing.
Like the others have suggested, get a tester and test each and every outlet before you plug in your rig.

The neutral and hot wires have to have been reversed in the 30A receptacle. Getting phase checker is cheap insurance against letting that happen to you.
Essentially what happen is that the whole trailer became energised because of the reversed polarity and when you touched the wheel, you formed a current path to ground, thereby receiving a small shock. It could have been a lot worse.
