Well, I cannot believe I haven't posted in this thread since last July. Holy Smokes.
We took the trailer two weeks ago to Mammoth Cave Kentucky.
While not off-roading per se, it did give us some beautiful road time and we were able to find (thanks to a Ranger in the supply store) a remote little known campground that is where a ferry once crossed (fell victim to the Government shut down and never reopened when the Gov't started back up again).
We only had a one other camper in a site that once held 12 campers and I think one night there were two others (usually gone the next morning).
The campground was on the river. First night (even though middle of May, we liked to froze to death (got down to 37 degrees- NOT normal for this time of year here!).
The Mammoth Cave State Park was fantastic. We saw more turkeys and deer ... but most of the spectacular stuff was underground!
We did both Mammoth Cave and another (and even more spectacular) Diamond Caverns. (well worth the price of admission).
In some places in Mammoth, we were 350 feet underground. And I didn't realize that Mammoth Cave is the largest cave network in the world (at over 250 miles long!)
Here is the site- note Green River in the back ground:
