I suspect some of the increase in efficiency was helped by it having a really bad .455 cd. When you start bad, any improvement is substantial. I suspect if I were to do the same with my van, which already has a cd of .35, I would be lucky to net the same percentage decrease, which would be a .26

The work is indeed nice and clean, though. Reminds me of an Airstream travel trailer. Looks like the rear tailgate was completely inaccessible; wouldn't that be a problem for a VW camper come tune up time?
