Badly grounded power pedestals
A lot of power pedestals on Mexican RV parks are badly grounded which can lead to nasty electric shocks if chassis is touched. We put a grounding cable into frame attached to grounding rod. Did notice...

Around three quarters of the RV park duplex receptacles I have checked over the years had hot and neutral reversed and the ground screw sitting all by it's lonesome.
Some parks had a merry mix of correct and incorrectly wired duplex receptacles.
Come to Mexico with an onboard energy management system and prepare to boondock 70% of the time. This is especially true south of Mazatlan and south of Mexico City. Especially true means >90% out of range of EMS parameters. Many facilities in southern Mexico have low voltage trippage during the day and high voltage trippage during the night. That is if you connect to a receptacle that has been wired correctly.

Isolating neutral to earth leakage can get complicated. But it is highly recommended to do so BEFORE leaving home. One experienced fellow had a two tier 40 amp switch in his cable stowage compartment that allowed him to reverse hot and neutral instantly.
And buckets of salt water are an excellent adjunct to any grounding system. Smear a light coat of SILICONE DIELECTRIC GREASE onto a copper plated steel rod before burying it to protect it from salt water corrosion.
Silicone dielectric grease can be smeared onto a battery post before slipping on the lug and it will still pass current to start the rig*. When I built the hotel I proofed each receptacle by a direct line to earth ground short. Popped the 30-amp breaker every time.
*Not a hypothesis. Fact. Repeated. Collected bet money from sneering unbelievers.
