Big tank looking to save gas

one idea could be to open the glass to a 10 degree angle (10 degrees down from level) and you could use a piece of 1x1 to hold it in place. you could measure it, cut it, and hold it in place with cotter pins or something. maybe have one on either side for stability.

the down side would be that you may get crap in the bed of the truck because now you have an opening.

all this is assuming you are speaking of a camper shell. you could have the pieces of wood completely removable so you could slide them on the top of the side rails when not in use. I don't know if they are all this way but my dad's old camper shell on his truck had a lip on the side rail so you could put stuff there and it wouldn't fall off (too easily). we used to ride to the beach in the back of the truck when we were little. that is before they came out with the whole "IT MIGHT KILL YOU" thing. and we never had seatbelts back their either. we used to pile up on bean bags. 1 truck + 6 people (mom, dad, 4 kids) = fun and cheap vacation transportation

my truck is a Suburban. not a pickup. didnt think of attaching it to the glass frame. may be interesting. anyone good with photoshop? I think it would look hideous. but who knows, I might be wrong. anyone got any ideas? also, would the kammback help for short hilly driving? or is it mostly a highway mod?

sorry for the confusion.

if yours isn't the one with the barn doors in the back, you could just use some plexiglass and bend your own, use some double sided tape to attach it to the glass and call it a day.

though this isn't a great example, here is one on a metro (but made of coroplast). it is similar to what I am talking about.

if you used plexiglass and used a heat gun to bend it into shape, you could make a similar design and it should be a lot sturdier and a little more eye pleasing.

you could make it out of these materials to start with as they are cheaper (sometimes free) and you could get an idea of the angle and what not.

it does do more with higher speed. the aerodynamics become a large factor at speeds over 55 (as a rule of thumb)

ok, well ill try to draw up a removable design. that way, if I cant stand the look, or if it gets in the way, I can leave it in the barn til I do a long highway trip. ill price some plexiglass or look for some around here
