A Body Road Trip Car

While I would consider it, as a long trip car (cross country) it'll never happen. We have put 600 miles in a weekend on my son's '67 Dart GT convertible (440/18-spline/3.23SG) that was getting around 15 mpg. My Barracuda will have all that I need to be comfortable for a trip (AC, cruise, probably heated seats), BUT my wife needs something more comfortable going cross country so we're diesel pusher shopping. Then we will get a 20' enclosed car trailer for the Barracuda. No motels, the car stays secure, and my wife can sit on the couch or in a comfortable captain's chair while traveling.
