Question Aerodynamic work trailer.

When we sold the Saturn vue that left us in a bit of a pickle for carrying things.
As the new car would be my wife's she had most of the day in it. I wanted a wagon, but I was informed that is what old people drive.
Interestingly enough, the Jetta can fit 3 adults and a 6' ladder.
The problem is we sometimes need 2 8'ladders and a 6'
This car is NOT getting a roof rack, period.
The other option is to drive the truck (<20mpg)
This will also replace our camping wood/dirty/wet stuff trailer.(currently a 4x6 box)

So I've spent some time designing a tapered trailer for work.
It needs to be 100" long for the ladders and 32" tall in the front and 62" wide.
Here is the big question, I expect to use plan taper.

What benefit/loss will there be if I make the top/lid flat vs tapered?


Losses:

True kamm back air flow

Benefits:

Flat surface to work on.
