Topper while pulling TT help MPG?
I'm curious has anyone had experience with a topper while pulling a TT? How does it effect MPG vs. no topper? I'm thinking a truck with a high topper would help make the truck/TT combo more aerodynam...

Not sure anyone has said exactly this: It would not surprise me if a topper affected MPG a little.
But what most of these posts correctly point out is that most campers are HORRIBLE aerodynamically, so the effect of the topper is going to be very mild (if positive at all).
When you look at all the doo-dads that semi trucks have (air dams on cabs, newer curtain things below trailers and sorta-partial-tail cones, I would not want to totally dismiss the effect of a topper, but you also need to consider that a truck is running "nearly-continuously" so those savings add up a bit quicker.
So yeah, if you want to boost your mileage meaningfully, slow down. Get the topper to provide a good, dry cover.
