Yes


For the past two years, I've been towing an open deck car trailer to various race tracks.
Trailer: 1600 lbs
Car: 3600 lbs
Extra set of wheels on the tire rack: 200 lbs
Tools and cargo in the car: 200 lbs


So that's about 5600 lbs (most likely a bit more), plus a crap load of cargo in the back of the truck. Mileage is going to vary greatly on route and traffic.
I recorded the following numbers after each fill-up:
12.70 Tow to PMP
15.00 Tow to PMP
13.80 Tow from PMP

10.80 Tow to WGI
14.30 Tow to WGI - All highway
12.40 Tow from WGI

13.10 Tow to NJMP
13.60 Tow to NJMP
11.90 Tow from NJMP
11.70 Tow from NJMP

12.20 Tow to WGI
15.90 Tow from WGI - All highway
13.10 Tow from WGI

12.20 Tow to WGI
15.70 Tow to WGI - All highway
12.40 Tow from WGI
