While its a little west of Austin, Sunset Point RV on Lake LBJ in Marble Falls is a pretty good park. They'll have almost every site big enough to park a big rig. Marble Falls is a good town. If you go in the spring, April especially, the blue bonnets are blooming. The area can be really enjoyable. Burnett (about 30 miles north) does a great small town festival.

You're close enough to Austin to get there, but far enough away to avoid the traffic!
