I have an '01 5.3 and an '09 6.2. The 5.3 was my workhorse tow vehicle for several years. It was sufficient.
The 6.2 is a monster. I average 12-13 mpg around town, partially because I can't keep my foot out of it. 400+ hp is rather addicting. Mated to the 6-speed, it makes for a very easy tow.
The new 6.2L is an absolute brute, there is just no comparing the two.
I suspect the mileage towing would be the similar as the larger engine won't be working nearly as hard, if fact I would not be surprised to hear that the 6.2L was actually a more efficient tow vehicle.
The rated MPG's of both trucks should give you an indication of the mileage penalty when driven empty.
Is nicer to have it and not need it than to need it and not have it.
JMHO of course.
