Congratulations on your new Jayco! Be sure and check out the state parks in Texas; my wife and I do most of our Texas camping in the parks rather than in commercial parks. The following link is to the Texas Parks and Wildlife website section on finding parks by region of the state:

You may want to purchase an annual state park pass; it gives you free entrance to all of the state parks for one year as well as three nights of camping at half price. We use the above website to check out parks, especially the layout of the campsites, before each trip. We usually make reservations by phoning the reservations office because there is no fee for making reservations by phone. Oh, you do not need a state fishing license to fish in most Texas state parks.
One final suggestion (which I have previously made in other posts): fire up your furnace with the windows and doors open because the first use will produce toxic fumes that set off your smoke detector. This information is essentially hidden in the furnace manual.
Glad to have another Texan as a member of the Jayco Owners' Forum!
