Hi Matt and welcome to Ecomodder. If you search for posts by KamperBob you may find some info about towing trailers. Your ideas #1 and #2 are on the right track. Articulated gap fillers between the tow vehicle and trailer are better, and of course a tail cone.

You posted all your questions under "aerodynamics". You may want to split parts of this into another thread. Is there any chance of trading your slushbox gasser for a diesel with a manual tranny? You could run a biodiesel blend most of the year in your area and this would be a better tow vehicle IMHO.
60 mpg hwy highest, 50+mpg lifetime
TDi=fast frugal fun
