IF you are having current fluctuations without
you changing the load, that is caused by VOLTAGE
(driving force for the current) fluctuations.
Get a small voltmeter ( a few dollars at WalMart
or other stores, or borrow one from a neighbor
or the management of the park)......plug it in
and see what your voltage is......should be between
say 110 volts and 130 volts........will decrease
as you add load.........if it changes withOUT
you changing load (or an automatic change such
as an airconditioner cycle on/off), there is
a power problem with the circuit feeding your R V.
Have the campground get that repaired.
