Steve, thanks for the real world input.  I've considered something bigger that would require more of a tow vehicle but now is a terrible time to try to buy something new or used.  The more I read, the more people are concerned with frontal area, which I get and given my intentional plan to avoid the interstate as much as possible and stay within 200 miles of home, I'm hoping being the slow guy doesn't cause too many problems.  It shouldn't if the speed limit is only at 55mph on a back road anyway.
