The Apache Trail starting at Lost Dutchman State Park is an awesome, beautiful drive passing a couple lakes. Definitely drive it with your towed vehicle as a day trip.
However, don't take your RV on it. You won't like the narrowness of this gravel road. 60/70 is the route you want to take and it's also a scenic one - but paved and wide.:)
