I have a Toyota HiLux and the other day saw one in Brisbane,Australia with a canopy with a slanted top. It look at bit like the slanted back of a Military Hummer. Does any body know of a company that makes canopies with slanted roofs. Have a look at this hummer, it has a slanted back-But is not removable. http://www.gadzooki.com/wp-content/uploads/2007/03/humvee.jpg
