The rational is that it is cheaper and easier to make the transition to the flat end at the front. Like everything else in this business it is driven by the numbers.

Manufacturing cost rules everything. It's much cheaper to make a laminated roof flat as you already have the equipment used to make the wall panels. In Lance's case they most likely do not move enough product to justify the cost of the specialized equipment to be able to do this.
