I would suspect the weight in the truck would be the leading culprit out
of all the other things you mentioned. Some place I remember reading
that for every few hundrid LBs weight you add, you could expect to see
something around a 1 MPG drop. I can't confirm that but I know I read
it in some manual somewhere. (I think that refered to payload and not
trailor towing)
I just dropped 480 LBs into the bed of my Dak (going to up it to 600)
for the snow plow counter weight. And I just filled the gas tank up on
the same night - - should result in some interesting MPG nubers.
