I can pull the largest U-Haul trailer (6x6x12) behind my CTD at 18-19 mpg loaded or empty (58-mph/1,725-50 rpm; two 700-mile round trips; .79 of solo). Same height as the bed topper. Adjustable hitch to "level" the trailer. A very stable trailer but hardly aero.

An aero all-aluminum travel trailer takes a penalty of 30% whether we speak of a 1965-spec tow vehicle or one of 2015.

Look to threads on enclosing gap from truck to trailer on this forum. Best truck spec (turbodiesel, manual trans and 2WD) plus a teardrop or boat-tail trailer "matched" to truck is going to average above 20-mpg as a combined rig, IMO , given long distances travelled. Weight is not much of a concern.
