My neighbor had the same problem. It turned out to be the electrodes in the hot water tank were fried. He had winterized the camper and drained the tank but did not turn the switch off on electric and he was still using the camper pluged to the pedestal. It took a while to figure it out
He had to have an OPEN GROUND conductor (the primary fault) in order for him to feel any ill effects of the second fault in the water tank. With a properly grounded frame the tank problem may have caused a breaker to trip, maybe not, but the skin would not be hot to cause a tingle.
