Garner State Park hands down.
We also like Garner SP. But in the southern Hill Country, we prefer South Llano River SP near Junction and Kerrville-Schreiner Park (former SP) in Kerrville. K-S Park has FHU sites, as well as W/E sites with 30-50A power. SLRSP has W/E sites, huge trees, river fishing, and a terrific bird blind. Garner has canoeing and kayaking, as well fishing and hiking. All of them are great campgrounds and, using I-10 with your tv or toad, close enough to visit both San Antonio and Fredricksburg on separate day trips.
We also prefer State parks and COE campgrounds to RV parks. So when we spent a month in Texas one winter, we invested in an annual Texas state park pass to save on the day-pass fees. We stayed in 10 different SPs for a total of 24 nights, so more than paid for it in fee savings.
