Orange plug means isolated circuit. It's not so much that they have special power requirements, it's that you don't want feedback from other systems. You don't want the guy polishing the floor sending feedback to your heart monitor. Same with the orange computer plugs. Motors sends spike when they start/stop. And for computers, low voltage (brownout) is as deadly as high voltage (spike). Computer switching power supplies are fairly happen anywhere between 100 and 130 volts.

For an RV, the simplest way to protect electronics is with a quality UPS. You can buy power conditioning equipment, but UPSs are readily available and will suffice for most. Particularly if you have the capability isolate your electronic's circuits.

If you're one of those people who have installed large banks of batteries for off grid time, you can redesign your system to be pretty resistant to bad power. Run your internal systems from an invertor and use shore power to charge the batteries.
