Wow.. John you have been great!  Thanks so much.  Let me ask what I hope to be the last question.  When I bought my trailer (used) the seller had the RV plug (male) plugged into an adapter, a short plug, that on one side had the female 30 A diagonal RV configuration, but the male side was just like a normal grounded house plug.  He had the RV plugged into a common household extension cord and that ran the lights. If I understand your advice, then I could use that same adapter, plug the RV cord, with adapter into the 120v/20 plug on the generator and it should work.  All I would need to do is know the WATT usage of each device and dont run anything simultaneously that exceeds the output of the generator?

Your license is safe, dont worry, I just need an answer.  If I understand the two "NORMAL" plugs like I see in my house carry only 20 amps each.  To get the 30 I need, creating a Y with 2 normal males on one end and 1 Female 30 receptacle on the other would give me the sum power of 40 amps total to the receptacle of which I would only use 30.  Does this limitation apply to the 4 blade twist lock.  Does that one receptacle have the full 40 amps coming from it, or is it also 20 amp max.  If it is 40, then I would only need the one receptacle, the 10awg cable, and the 4 blade male.  Your response is great, just want to be sure what I need to do at Lowes or HD, and what to buy.

I have searched the internet far and wide and have yet to find someone who can tell me the answer to my question, in terms I can understand.  I have a travel trailer that runs off of 30 AMP power supply when I "plug in" at camping locations.  I purchased a Porter Cable BS500 gasoline generator that has two 120 v plugs (like household plugs) and one plug called an L14-20.  I know the generator puts out 5000 watts, and it has two circular 20 amp circuit breakers.  I am looking for a converter, plug, or some other way of powering the 30 AMP inverter in my RV from my generator.  That is the only reason I purchased the generator, and if I cannot find such a converter or device the money was a waste.
