Running AC off of my home's current/Please Respond

Thank you everyone. I do not have a "special RV line" at my house. It's unlikely that I will get one. I just ordered a volt meter for the RV. I'll use it as soon as I get it. I do have a heavy duty extension cord, but I don't remember if it's 30 amp. Not sure that I knew what to look for when I bought it. It is probably longer than I should be using. I'll check out all of this. Thanks again for the help. There seems to be consensus around some basic points. Those are what I'll go with.
