But with the "Camco" dogbone, it would only light up to 3/4 charge. So I assume, there's something wrong with the new adapter because when using my old cheapo adapter, it goes immediately up to "full charge". I'll take your advice and buy a "Marinco" adapter off Amazon and hope it does the trick. Thanks, Marshall, for the tip.

That panel is a reflection of the voltage of the battery(s). When plugged into shore power it should read full as the voltage of the converter charges the battery (dc volts) When not plugged into shore power it should indicate the relative voltage of the battery. I say "relative" as that is not an accurate device. It will not indicate the voltage from the shore power (ac voltage). So that panel is not an indication of what the adapter is delivering from the shore power.
I have a digital voltmeter plugged into an outlet that will read the accurate ac voltage in the camper when plugged into shore power. They are available for less than $20. For battery voltage, I installed a dc voltmeter (marine grade weatherproof) on the battery box which sets on the tongue of our travel trailer. I did that so I know the battery condition before I operate the tongue jack.
I would suggest looking into an EMS (energy management system) as that will protect your electrical system from low voltage, high voltage, mios wired pedestals in the campgrounds.
