>>Why Starwagon out-coasts mine down hill? Loren is just allot "slicker". 

Hey Phil,
That makes your tires roll 4% further per revolution than Lorens.
I wonder if your bike rack and canoe rack would add much air resistance compared to Loren's van.  I know you had a bike on the back of your van and canoe on the roof.  I also think Loren's van sits a little closer to the ground.   (Check out the panorama picture from Catherine Creek that Loren posted last fall. www.pbase.com/labusch/oregon2005)  When you are flying a box down a hill any little air flow advantages probably add up.
