I have a 2005-vintage RV-220-50 with no other surge-suppressor device. How many joules do I have (if any)?
Hughes Autoformer RV220-50-SP 50 Amp Voltage Booster with Advanced Surge Protection
Also, the orange light on my unit is flickering when plugged in and the source current voltage checks out okay. This has occurred on a couple of sources and far as I can tell, my unit is working. Does this happen?

According to the manufacturer, yours has 733 joules surge suppression per line = 1466 joules total and 4500 amps spike protection per line = 9000 amps The yellow (amber) power light should stay on. Maybe your's has a loose connection or is just not working correctly. It could also indicate the ground your plugged into at the power pole is not good. and you should move to a different pole.
