When choosing a tow vehicle and trailer, in addition to the weights you will also have to consider the frontal area of the trailer. Looking at the
Ford towing guides, for example many smaller vehicles are limited to 20 or 30 square feet of front area of trailer. (7 1/2 feet wide but only 3 to 4 feet high). Better suited for a pop up.
Our one and only long trip with a 2000 Ford Windstar and HTT trailer averaged only 4 mpg. Worst trip ever.
On the bunk end question, the bunk ends are not that heavy, but could be a bit of a challenge to get fully closed and latched, depending on your dexterity.
