50 Amp Rig to 15A house power.
Looking for advice on how to connect our 50A fifth wheel (2014 Alpine, love it!) to our 15A house power while loading or cleaning the camper, and conceivably for longer periods. I have a 50-to-15 adap...

IMHO The minimum plug you should use is a 20A plug on a dedicated 20A CB and here's why. The 15A plug is typically one of several on a 20A CB. If any other plug on that circuit in the house is using power then the voltage is already reduced before you plug in the RV.
So you run the risk of lower voltage and while checking the voltage is a great idea loads do change. So do you really want to watch a voltmeter all day?
So lower voltage is much more likely on a 15A plug than 20A, 30A or 50A plugs.
So Keystone is right even if they have no clue as to why they are suppose to say what they did.
And yes I have used 15A plugs at friends house in spite of the above.
And here's another wrinkle: My house has 8 outside and garage plugs on a GFCI with a 15A CB and 270' of 14 gauge wire. When I plugged in my saw in the last plug it would not cut hot butter. And this circuit is 100% to code and meets 0% of my expectation for reasonable loads but saved the builder a few bucks. If there had not been a 20A plug on a dedicated 20A CB nearby I would have installed one. I did installed a 50A plug for the RV.
