How long have you owned your 2011?
4wd 5L bought 9/11 now 9k miles. Started at 18.3mpg new with a topper I dropped to 17.5mpg, now with winter fuel and idle time 16.2mpg. The engine was a little noisy on the coldest mornings. The engine takes a while to make hot air.
Got my 5.0 2WD in September of 2011. Got about 5500 miles on it. Took it from Las Cruces NM to Anaheim CA and back for Christmas and not one issue with the truck (except the pesky SYNC / IPOD issues). As for the kids however, plenty of issues with them during the trip...
