I have often wondered if 4 vs 5 wide made much difference in mileage. Most cars, including my Jetta sportwagen, are about 5 ft. wide. In theory it should punch an initial 5 foot wide hole in the air which starts to collapse but the tear then re-opens. The turbulent air should be easier for the tear to re-open then if it had to do the initial breaking. I wonder how much extra drag that extra 6 inches per side makes.
What ever it is I for one will not give up my 6 inches of bed.

I certainly am no authority on the subject, and it really is what you as an individual want. My son Pete's is as wide as his minivan, and his mileage drops tremendously. He also brings ALOT of stuff.
I may have gone 5', and never known the difference, but a "true" teardrop is 4' and that's what we wanted. If we build again, we would probably go for the 5'. Now, if we had a "Finn" to fit in, we would definitely go with the 5'.

Hope Cheri's treatment is going well. Maybe we'll see you in June.
