Kentuck campground is definitely NOT big rig friendly, had a hard time with our little 18' trailer! Luckily OP has a rig that is perfectly suited to the campground, hard to get much easier than a 21' RV without a trailer or toad!
Btw we were in site 194, perhaps the hardest site I've ever seen at a campground. It's located on a switchback, but the natural entrance and lineup for the trailer is actually pointing downhill towards the reverse of the traffic flow. The wife had to be super careful getting the rig going in the right direction while avoiding putting the nose of the TV into the hill that formed the switchback. It probably didn't help that we arrived after dark, but the angles would have been the same with or without light and we had the advantage of time since we weren't blocking the road for anyone else.
