RE: any 4.7 2wd owners?
I have an 06 2wd with the 4.7 and a manual tranny. I'm getting around 17 mpg, driving roughly 65% highway, 35% city. I've done a few tanks that've been all highway, and it'll get better than 19 mpg there. I'm putting a topper on it in the next few weeks (I just ordered it Friday) and I'm interested to see what, if any, difference that'll make. I've also heard that taking the muffler off (and leaving the two resonators) is a good, cheap way to gain a few mpg.

I have an bone stock 06 QC SLT 4x2 4.7 3.55 rear and tow package... Mostly highway (75%), I get 17~17.5mpg at 75mph - AC on or off. It runs about 2100 RPM cruising, not much different than 65. I had one run of 100% highway and got 18.5mpg. I only have 4200mi on it so far. I'll be adding a tonneau - we'll see if that does anything or not.
