i am assuming this would be the combination of some sort of tow vehicle fairing and whatever i do to the front of the TT?


yeah, and i want to learn how to use these kinds of materials anyhow, so, it makes a lot of sense.

Do you think that a belly pan under the front makes sense also, given that it is simply cost of materials and time?

from what i've been able to gather, the boat tail is probably going to be the simplest to implement since i don't have to worry about clearances between the trailer and vehicle.

the exterior heigth of the camper is 78 inches, the durango is 70 inches, so, that shouldn't be particularly complicated to overcome.

Thanks for the input!
* the shorter the 'gap' the better, so that's good news.
* on the roof is way out ahead of nothing. technically, you'd follow NASA's lead, creating an interface between the back of the tow vehicle which 'blended' to the leading edges of the trailer. An inflatable structure attached to the trailer face, which deployed while underway, could do this hat trick.
We want to think of the T.V. /Trailer as an aerodynamic singularity ( you'll never see 'gaps' in commercial airliners, submarines, kayaks, torpedoes, or dolphins ).
* any 'belly' modification is worthwhile ( my truck is fully belly-panned, as well as all my trailers ). They're designed with diffusers as well, the trailer being a natural extension of the truck' diffuser geometry.
* yeah, if you learn how to do composites, there'll be no limit to what you can create.
* it doesn't hurt to know how to do 'upholstery' as well. Retired gear-drive sewing machines from old high school home economics classes can be had for a song, and they're capable of fabricating extremely lightweight, aerodynamic structures.
* any 12-VDC HVAC blower out of wrecked cars or trucks is ample for inflated aerodynamic add-ons.
* The boat-tail needs as good a quality of onset flow you can give it. If you can clean up the flow coming to it, it will reward you with the best performance.
