Reason? If NEC is not followed it opens manufacturer to lawsuits. Article 551.41(C) Ground Fault Circuit-Interrupter Protection.
Where provided, each 125-volt, single-phase, 15 or 20 ampere recepticle outlet shall have a ground-fault circuit-interrupter protection for personnel in the following locations:
(1) adjacent to a bathroom lavatory
(2)Where the recepticles are installed to serve the countertop surfaces and are within 1.8m (6ft) of any lavatory or sink.
Exception No.1: Recepticles installed for appliances in dedicated spaces,such as for dishwashers, disposals,refridgeratores,freezers, and laundry equipment.
Exception No:2 Single recepticles for interior connections of expandable room sections
Exception No:3 De-energized recepticles that are within 1.8m (6 feet) of any sink or lavatory due to the retraction of the expandable room section.
(3) In the area occupied by a toilet, shower, tub or any combination thereof
(4) On the exterior of the vehicle
Exception: recepticles that are located inside of an access panel that is installed on the exterior of the vehicle to supply power for an installed appliance shall not be required to have a ground-fault circuit-interupter protection.
The recepticle outlet shall be permitted in a listed luminaire(light fixture). Arecepticle outlet shall not be installed in a tub or combination tub shower compartment.
This is why electricians are so expensive. We have to follow all code articles or risk losing our license not to mention the legal ramifications. However the "Purpose of the code is the practical safeguarding of persons and property from hazards arising from the use of electicity." Don't assume you can follow some parts of the code and not others. The NEC is there to protect you even if you think you know better.
This has nothing to do with the OP however, I just wanted to point out what recepticles are protected by a GFCI and where he might find the GFCI that is causing his grief. Remember any downstream recepticle is protected by the GFCI. If you don't find a GFCI call a licensed electrician and have them install one because someone "knew better" and removed it from your motorhome.
