We have the 5.3 in our 2005 Suburban. Hwy is 20-21 if you go easy (65), streets is about 16-17 if you take it easy. Everything changes if you have a heavy foot!
Towing gets 12.5-13.5 depending on hills, overdrive or not.
It actually gets good mileage considering the size and weight of the vehicle. I think you will get slightly better in a pickup.
Good Luck!:D
