Currently running a 2011 5.0, been very good so far, no issues at a bit over 30K miles. Highway mileage is 20-21.5 (US), city/suburbs is 17. Pulls 5300 lb trailer nicely, last trip was about 12 pulling the trailer through the mountains.
My brother runs a 6.2, slightly less mileage empty but definitely more power. His hauls his 8K trailer nicely.
