Disclaimer: I am biased towards COE campgrounds. Cheap, ample grass, trees, water, blue sky and stars at night. Usually a paved pad, reliable utilities, picnic table, fire ring, grill, friendly volunteers. Did I mention cheap? With a National Park Pass you get 50% off so nightly rate is usually $11-15 range. How can you go wrong. Almost always good site spacing, 20-30 feet. Almost always well maintained. Waaayy closer to camping than commercial RV parks. 

Cranes Mill is 4 of 5 on COE scale, paved pads, pretty level. Good spacing, generally 25-30 feet. Hooded picnic table with usual fire ring, grill. Excellent bath houses. Canyon Lake was low when I was there (Nov,'22) but still fishing and boating activity. Small towns/shops <5miles, major shopping 15 miles. I'm going back in Feb'22 for another stay.

Good cell coverage - Verizon, 3bars LTE, 10+mb down, ATT 3bars LTE 10+mb down. I work remote so this is important. No issues in my ten day stay.
