As others have said, Hicks Field and Northwest Regional airports have lots of RVs. Jay Pratt at Hicks always has several RVs being built, and Northwest has Walt, Randy, and Doug's hanger.
If you go to Northwest Regional, you should stop at Roanoke to grab a burger at Twisted Root, or get some BBQ at Hard Eight. If you want a Chain Bruger then Whataburger is the official Texas burger place (according to my son and his friends!).
Have fun looking around! I would take time off work but just came back from an 11 day trip flying around North Carolina, South Carolina, Georgia and Alabama and have to catch up on work.
