What hardware lowers high voltage?
deleted...I try again later.

OP specifically said "continuously regulates" not limit. I would take this to mean that he wants to maintain voltage inside his RV within a certain range despite what the input voltage could be. A surge protector/EMS does not do that and cuts power off at a specific high (or low) voltage.
It sounds like what he may need is a constant voltage transformer along the lines of this one: constant voltage transformer This will regulate both high and low incoming line voltage. If this is what the OP wants, I would suggest go talk to an electrical wholesaler and see what's available. I don't think it will be cheap.
There are RV "autoformers" that regulate voltage, but they only boost low supply voltage. Hughes and Franks both make autoformers.
If the incoming voltage was always on the high side, in theory, it could be possible to use a standard autotransformer with fixed settings that would drop it to an desired level. Not likely to be practical in reality tho.
A problem is that sometimes a utility will set the taps on a distribution transformer at a higher than nominal voltage so that when demand on the system gets high, like in the summer with everyone running AC units, the voltage will not drop below a certain voltage. More common in rural or remote areas.
A PI EMS unit will cut the power off when it reaches 132 volts. If it's just occasional high voltage levels that the OP wants to protect against, then an EMS would be the easiest and cheapest way to go. But if it happens frequently for long periods, then I would look at constant voltage transformer (depending on cost).
