Fall Creek Falls is a nice park - one of our favorites actually, in any state - but some of the roads in the campground could be interesting for you (sharp turns, steep inclines, narrow width, lots of traffic.) As for SR-52, if I recall correctly, the road has a few tight twists near the river crossings but is not overly bad otherwise. Both of our campers handle that sort of thing much easier than something 37' long though, so I can't speak directly from personal experiences navigating those locations in something that length.
