You might check with Dreth, he used the RV side on our last visit to DT
Dreth took his own rv, if you are refering to the rv's/trailers DT has for rent, then I can help you, they are way nicer than the cabins. The cabins are very basic. The rv's imo are much better, they have a full kitchen/full bath, bedrooms (we normally stay in the one called Jack Rabbit).
