My guess is that if they use a standard length, they can use the same duct regardless of floor plan and then drill the correct locations for the vents. They can also change locations easily. For your second question, as long as there are no leaks in the extended duct, then it shouldn't matter since it is just dead air space. However it certainly won't hurt to block off the un-used duct and since air leaks are a high probability, it might help a little. I used 3/4 inch rigid foam and caulk on my '04 Cruiser, have not done the same thing yet on the '11 Cruiser.
