Newbie! 30 amp to 20 amp converter
HI folks, I'm brand spanking new to RVing. The trailer I am attempting to make "usable" is a 1988 Companion Classic. Needs work. My question: when using a 30 amp to 20 amp plug converter do...

Some people should not be giving electrical advice; they don't know what they're talking about. There definitely is 240V available in a 50A RV; it's just not generally used.
So are you saying, I can plug in a 220 volt appliance into a standard 50 amp outlet at a campground and get 220 volts, yet take a "normal" 50 amp plug for an RV and plug into the same outlet and get 50 amp / 110 volt?
Yes, you can.
There is 240V leg to leg. If you need 240V at up to 50A, you (or your appliance) uses those connections and doesn't connect to the neutral.
There is 120V from each leg to the neutral. If you need 120V at up to 50A, you connect between one of the legs and the neutral. You can do that twice, once on each leg, to run two 50A 120V loads simultaneously. You cannot, however, run a single 100A 120V device directly so this is not a 100A 120V service, no matter how much some people here like to call it that.
The voltages of the two legs with respect to neutral are 180 degrees out of phase with each other, which is how this is possible.
