For extended traveling, we really liked our Trail Lite B+.  A Phoenix Cruiser would be similar, although pricey.  You'd like that a lot better than a Class B, I think.  How much do you care about the actual driving experience?  A Class B would be the easiest to drive, although the Sprinter B+/C models are quite good also. Our Trail Lite Chevy was pretty easy to drive too. Very nimble. 
Our Sunseeker 2300 Class C Chevy gets an honest 10 MPG at 65+ MPG. The Chevys get a little more MPG than the Fords, and have more leg room too. It has a lot more room and storage than our small B+ did. It handles "okay".  Meaning satisfactory, not unsatisfactory, but not like a van or car. My wife drives it with no fuss, and she's not courageous.  We can go anywhere within reason, including into towns.  We drove it to, and parked it in, Jerome AZ with no issues; some people will appreciate that. Let's just say you would not want to take a big MH there. :)
