First of all,I had a 5-hour phone conversation with the Femmebot last night so I'm not as far along with the data as I would like.
And I'm close to the deadline for my income tax and will have to re-direct my energies for awhile.
Here's some of what I've gleaned so far.

General observations:
The data comparisons in some cases are apples and oranges due to different test velocities.
This year,with the trailer,MPG was better than last year without the trailer,but overall maximum cruise velocity was lower by 10-15 mph depending on the segment.
--------------------------------------------------------------------------
The Cloudcroft-Denton 55-mph testing will be a continuing protocol and I did have results for past years (this run is where the CRX scored 82 mpg at 55-mph in 1995 ).
--------------------------------------------------------------------------
For Artesia-Denton:
This year,with the 682-lb weight penalty,the 33.918 mpg is lower than last year's 34.264 mpg without the trailer,although,was 2.105 mpg better than in 2009 when I made the same run,also,of course,without the trailer.
--------------------------------------------------------------------------
There is more data,but I'm kind of burned out right now and I'd like to catch up on other's threads.
--------------------------------------------------------------------------
Loose conclusions:
On flat land the trailer should be zero mpg liability.She weighs as much as the 'production' trailer,with a complete Nissan Leaf Lithium ion pack [410-lbs (186kg)].
It should be possible for a plug in EV to pull the trailer,containing a second pack and double its range ( highway only!).
When 'finished' she may show a net 'gain.'
Mountain driving shows a penalty I think.
It would be instructive to take a bone stock T-100,strap on the trailer with no other mods and see what it would do by itself.
--------------------------------------------------------------------------
I'll add data as time permits.
She's still an unknown quantity,but the 47.9 mpg run illustrates the relative importance of streamlining.Getting the Cd down lower will be the same as a continuous tailwind when on the highway.See you all later.
