Sorry I haven't followed up this post until now.
We took or new 24RKS on it's maiden voyage last weekend. Went to a local camp ground. Everything works as designed. LED lights are nice, skylight in kitchen and bathroom are great. Windows don't open very far, flooring looks nice but appears to scratch easily (beware of small stones, gravel, etc.). Not sure what it is made of, but has a plank like appearance.
Overall we are very satisfied with this unit. With a little care it should last us for a while!
