MPG difference with tonneua cover
i put an extang cover on my ram.. the kind its like a tarp that clips into the sides and it has 3 support rails, cab, bed, and center of the bed.. i noticed a .5 to 1 mpg increase.. depends on how i drive of course.
i had a fiberglass cover on my 1999 gmc with the 5.3L never really noticed any mpg diff after i took it off but i sure as hell noticed a diff with wind drag at 100mph....could cruise at 100mph with that truck let off the gas and she would stay cruising forever after i took it off......lost it on the street!! it never did slide through the air like that ever again at 100mph.
It seems like a hard cover would save just enough drag to make up for it's weight,kind of a wash as far as mpg's. More attention should be paid to if a cover will fit your needs or not,I don't think the MPG difference will affect your bottom line very much.
would you buy it again? i need space for my mountain bikes, and my kayaks, and for work i need a secure bed, so i'm not to sure what to do
I have a TruXedo cover on mine. Added a locking tailgate handle from Moe's the other day.
Keeps the bed nice and dry. Very little gain in economy.
Velcro on the sides and has a dual latching mechanism over the tailgate area. Rolls up by the back window for full bed access if needed.

how was the install on the tailgate handle?
Painless, just remove the 8 screws holding on the access panel in the tailgate and it is held on with 2 10mm nuts. Took less than 10 minuted to changes. Looks oem too. Key goes in under the handle out of sight.
