We are also in Rockport, TX. Park your TT so it can act as a wind block, a small plastic dish pan outside the door to stick bare feet in prior to going in the trailer, and small rug inside to dry off will help keep the sand down inside. You can also use baby powder to keep it off of you! A swish broom is handy to brush things off. Pay attention to the tide charts! Wash trailer off after leaving the beach!
