A Moka pot is the best inexpensive choice. Its a stove-top espresso maker, so works good for the RV. Use it with a battery operated milk frother (heat the milk in the microwave or on stovetop) and your good to go.
Moka Pot
^^^This.
The moka pot will give you a nice strong cup. Get the 6-cup version, that makes one normal-sized coffee mug worth per brew. I don't believe it meets the "true" definition of espresso though because it doesn't build up enough pressure.

..."moka" style machines...rely on steam pressure to force water through the ground coffee. Steam pressure is only capable of producing up to 1.5 BAR or 50 PSI of pressure. A true espresso machine must produce a minimum pressure of 9 BAR or 135 PSI (pounds per square inch) to force the water through a bed of finely ground and compacted ground coffee. The steam driven moka pots are often sold in major department stores for $75 or less. They usually include a 4 cup carafe. True espresso machines are pump-driven or lever operated.
I have no experience with the milk frother, though. Just adding regular milk has always worked for me.
