A couple of other options - both of which are flat-towable with no additional hardware:
Dodge Dakota 4x4 - our '03 Quad cab gets 18 Hwy / 15 overall. The newer ones supposedly get 20 or so. LOTS of people tow Dakotas. At 4500#, however, it msy be a bit heavy for your MH.
'08 - '09 Ford Escape AWD. 3200#, 24 EPA Hwy. Although we took delivery of ours last week, and according to its trip computer, it got 30.4 on the trip home.
