Well, I'm back! How's it going?
I've been looking for diesel box trucks lately, and am just not finding what I'm looking for, so I've decided to modify my camper a bit for the next tour.
My goal is to get 3mpg better than my current 7mpg.
I average 10k miles on a tour, and if gas is at $4 a gallon (hopefully less) at 7mpg that's $5700, at 10mpg that's only $4000. That 10mpg figure would be well within my budget for this trip.
Tell me if you think these mods will give me 3mpg.

1. Less bricky- I'll chop off the sleeper
2. All wheel wells covered, Also side skirts added
3. Small mirrors
4. Build small truncated tail
5. Air vent covers
6. Front air dam and partial grill cover (lots of wasted flat spots)
7. Fan clutch

That's what I think I can reasonably do before tour....
Will it give me the few mpg I'm looking for?
