Bedcover and effect on fuel
With all the experienced fivers, has anyone ever "tested" the effect of non-closure verses partial closure of a bedcover on wind drag and fuel efficiency while pulling their Montana?
I carry my fold-up bikes in the bed between the back of the cab and the hitch. Consequently, I partially close my Pace Edwards bedcover to keep my bikes out of foul weather. I don't know if I am doing an injustice (creating a partial vacuum) by partially closing it or not. Any experience would be appreciated.
(I know this issue will NOT create major fuel increases...since I get 7.5 to 8 mpg with my 8.1L). Thanks in advance for any ideas.
