RV hookup or camping in TX Hill Country

We have a 30A 125V electric RV hookup at our working ranch. You provide the RV or feel free to camp instead. Water is available but no septic dump. Have to be comfortable around a variety of farm animals (chickens, turkeys, guineas, ducks, jersey cows, donkeys, etc. ), semi feral cats, and standard poodles and respect the county burn ban if in place. Pets only if they stay in the RV for the safety of our livestock. Pastors/missionaries may stay free and help out with our confessional, liturgical LCMS mission (Christ Lutheran) in Johnson City.
