Rancher Will is right, Eureka Springs (in town) is not a place to pull anything. The streets are very narrow, no parking to speak of, and traffic is awful. The highways in the area, though, are easy to navigate, there are a lot of turns, but really gorgeous scenery. Eureka Springs is a fun place, especially this time of the year.
Highway 7 is a wonder in the fall, but I think you are probably too late for that color. Might not be as fun in an RV, though, unless you like constant turns.
Just don't wander off the main hiqhways and expect to be able to manuever easily, like most places in the hill country. Remember, WalMart was born in this area, and their trucks go everywhere!
But do watch the weather. That area is notorious for nutty storms that blow in and ice everything up, and they will get some snow, as late as March (been caught twice in March snows).
Many great state parks options, too, if so inclined.
