I fully agree Demian. I was just presenting an idea.
I have no intention of even trying to ask anyone to produce this thing.

However, if this thing could be made of nylon tent material it would be really light and
it wouldn't absorb water and mildew / get heavy like canvas /would be lighter and more durable than rubber )

(Just think of how lightweight that a nylon tent is. I'd bet I could lift even a large tent easily with one arm.)

The nylon fabric could be bought at any large cloth store. To make things less complex, it could be designed like a curtain that simply pulls back to meet the trailer.

( Minding the hot exaust stacks and any other such things of course.)

One more thing that I thought of : The middle section of the top portion of the Kammback could be pulled downward and secured when there is a cooling unit on the trailer. This would actually direct air right into the unit and it might even operate better than within the open section of a conventional setup.

I'll have to do some illustrations when I get back home.
