Most state parks have a 14 day limit.
Id give them a call and ask so you know 100% how long you can stay just the safe thing to do.
The Texas state park rules state: Generally, you can stay 14 consecutive days. Some parks have established other limits, with some offering weekly/monthly/seasonal rates. Check with the agent when making reservations, or visit the park’s website. For instance, Falcon State Park has established monthly rates for the winter Texans who come to spend the winter in Texas.
Best to call. Limits can vary
