That could've been my own answer, too.
I even argued at a cg with a kid who seemed to think we needed 240V in our rigs.
Where this all comes from, as you all have pointed out, is the 30A wiring.
Here is the caution I recall, one that says not to trust certified electricians. It comes from the same folks quoted above, but applies to the 30A.
It is imperative that the Electric Service used for RVís are wired correctly. DO NOT TRUST anyone, yourself, friends, relatives or ANY Professional Electrician. ALWAYS check out all RV Electric Service BEFORE plugging in the first time. The majority of the mistakes and the most damage to the RVís are made with the incorrect installation of the 120-volt 30 amp Service. For some reason people including Electricians just DONíT GET IT when it comes to the 30-amp 120-volt Service. All you need to do is look at the online Forums where RVís were damaged by incorrect installations.
Finding it sure made me feel better! For awhile, you guys had me convinced I'd lost my marbles.
A funny aside: having forgotten the distinction between 50A and 30A, I was at a cocktail party here in the air park, the conversation turned to the subject of an incoming visitor. 'Seems he was bring his own Class A, and was going to park inside one of our hangars. The owner had, in preparation, put an RV plug where he had a 30A outlet for an air conditioner. The fact that I'd forgotten the distinction was thankfully moot: after we talked he went and rewired the plug with diagrams downloaded from RV-oriented sites, preventing nasty damage to his guest's rig.
