[attachment=7478]A quickly drawn up diagram to answer your question. There are many ways to accomplish your goal, this is one.
Select the branch circuits you want to protect. Purchase a 100A 240V MLO (main lug only) 16 circuit panel which will become the "protected panel". route the selected circuits into this panel. Acquire a 100A 2P 120/240V transfer switch, either manual or automatic and feed it from a 100A breaker from your main panel. From the transfer, feed the "protected panel". No breaker is required since the circuit is protected by the 100A in your main panel. Purchase an INLET for 50A 3P 4W 120/240V and mount in a weather proof enclosure. An Inlet is a male pin panel mounted device. connect it to the "emergency" side of the transfer. A cord capable of handling 50A with 4 wires (6-4 SO or =) will serve as the feeder from your coach to the transfer. it will have a plug on one end and a connector (a cord mounted receptacle) on the other.
attached is a quick drawing for reference.
