We checked out this park and it is not too bad. There is a separate area for the short term stays. The road entering is tight and at the bottom of the loop is awkward around the trees. I would recommend only for shorter rigs.

What campers say
Diamond Jack’s RV Ranch is a quiet, secluded park with a relaxed, family-owned feel and reasonably priced long-term options. Lots tend to be spacious and pet-friendly, and there’s a pool and basic water/power service with a dump station rather than full hookups. The park is older and rustic; guests report uneven dirt roads and potholes and mixed upkeep of facilities. Management responsiveness appears inconsistent—some visitors praise the owners while others had trouble reaching staff. Tradeoffs are clear: good for a low-cost, peaceful stay if you don’t require modern hookups or pristine grounds.
