I don't currently own one. A neighbor does. imo, yes it gets a little less. It is primarily due to the tire differences. Pro 4x has all terrain, SV has all season type tires.
Driving pattern will be a bigger difference.
But if driven exactly the same, the pro-4x should be slightly worse (less then 1 MPG is my guess). Little lower gear, little taller ride height, little more rolling resistance.
But you will not see a huge difference. Only slight, probably closer to measurable only in a lab type of differences.
You can take the same truck and one person will get 21 MPG out of it, change drivers (routes, patterns, driving habits and all that go with it) and it can drop to 12 MPG.
As far as I know the gearing is corrected to accommodate the larger tires on Pro-4x models. My 2010 King cab Pro-4x 6spd average fuel economy is a hair under 19mpg.
All depends how heavy right foot is haha, 2016 Pro-4X KC with the 6spd here, no mods. Highway driving on cruise I've had it down to 12 point something L/100km. Truck is stuck in Vancouver traffic most of the time though, and gets on average right now 16.5 L/100km. But i do have a heavy foot, this truck is waaay too much fun to baby when I have a chance to open the throttle up
I've owned an '05 SE 4x4 and currently own a 13 pro4x and when they have the same size tires, they will have the same gas mileage. They're about the same weight, same gear ratios, same truck.
Not sure what models had the roof rack, but my Pro-4X has the roof rack that is missing on some of the base models I've seen, and I'm sure it has some sort of hit on gas mileage as well.

On my new pro-x, the gas mileage is the one thing I am disappointed with.
I got the 6 speed manual and the first 500 miles was on the highway in 6 gear 90% of the time and only got 16.5ish. Actually the first tank was 14 and then it got better. But frankly, my 1997 chevy s10 zr2 with that 4.3 liter 6 cylindar still gets 20 mpg. It is amazing that nearly 20 years later that the technology hasn't improved at least moderately. Luckily gas is still cheap.

I have a 2016 Pro-4, so no roof rack but it came with the Hankook P rated A/T tires. Honestly everyone has it about right here, it's what kind of driving you do and how you use that right foot. You can do a lot more I believe with the manual, but I've not seen anyone with an automatic that I could try so who knows. There are days I am just aggravated or whatever and subconsciously the right foot just hits that pedal a bit harder, other days it's not nearly as bad. For me, a lot has to do with what type of SXM channel I have on, whether it's calm and soothing music, or other.
That said, the best way I feel to determine how your vehicle is doing is to avoid all of that, and only look at what it's doing when you're on cruise control. Generally doing 60 would make the most sense. That removes the whole "driver" aspect of the equation at least. I have tossed on some pretty heavy addons in this first year, shrock rear bumper + full skids as well as some rather heavy duty rock sliders, and I have noticed it's not really capable of maintaining up to 20 mpg anymore even on generally flat highways cruising at 50-60. Not unless I go to premium gas at least. The truck is only going to get heavier as time goes by and I'm allowed to further abuse my bank account.
All that nonsense said, I generally try to aim for 18 mpg at the end of a full week and fuel tank for my DD to work and back which tends to be 2/3 highway driving and 1/3 stop and go city. Sitting at 18.3 by the stock truck MPG meter as I parked it this morning, and I reset the meter each time I fill the tank up. Worst I've ever seen was around 9.5 mpg when towing a dive boat that was at or exceeded our towing rating, best I've seen was about 21-22 mpg with cruise on and full premium gas.
I recently switched from LT 10 ply 265/75/16 to P rated at. After 500 miles it looks like I picked up about 1mpg. Was getting 16 mpg average under all conditions and now about 17.
