KamperBob,
i'll never consider going smaller with the bed.the whole reason i drive this truck is to move wood and chips etc.the larger the bed-the fewer the trips,making FE almost meaningless.by the miles driven less because i can take more at once,and all the time saved by doing so as well.since its a 100% work truck only,you know what they say time is....
truck duty first.fuel economy will always be secondary.
iv got a small car when i need to just haul myself around.
however if you have some ideas for the bed in its current state,id be interested to see some ideas.
im not going to get hardcore,like many here do.for example trying to close up gaps between trim/headlights etc.
all im looking for are the big obvious things,and a few smaller.but nothing tedious.
this truck doesn't move,unless it's to make $.however,i don't want to be like most folks,who just do nothing about aero once they setup their work trucks either.fuel costs way too much now,to do nothing.
basically,if i can gain .5 (true average) mpg from aero modding,then im a happy guy.though,if there is obvious room for improvement after that,i won't stop until most here say iv got all the big basics covered.
