9mpg towing...normal I think?

Hey there, typically I don't fret too much over fuel economy as I figure there's not much I am going to do about it...still gotta drive. However I am slightly concerened for an upcoming trip. I intend to head out from Colorado up to the tetons, then head over to niagara falls, then to upstate NY, to the keys, then back home.

I tow skidsteers and pallets fairly often but I noticed towing my camper (2004 arctic fox 30u, bumper pull) my mileage is a lot worse, bout 9 going 75.

So my question is, is this typical, I am spartan tuned, and straight piped, thats all, oh and I am running 35'sx13 duratracs

Furthermore, I figure the best tune empty is the 275, towing I backed it down to the 210tp, is there a better option, the truck yanks the trailer just fine so I don't necessarily need the power more than I would like better economy.

And as much as I would like to just go slower I foresee I will want to go the posted limit as its a lot of miles

Thanks

Oh and thats not a hand calculated 9, the meter says 9 and change so I figure with the larger tires, and the fact that typically the meter is inaccurate its actually probably pretty close.
Last time towing it said 9.6

hmmm... I towed 9k up through the mountains a while ago and managed to get 12.3 hand calc'd on my 38's. I'm a 3.55 gear ratio though so maybe that has some contribution?

I am not sure if it is normal or not. I would say it is ball park if your truck were stock.

And I thought I would also say that the trailer weighs aroun 8500 lb empty, and sits a touch higher than most, I think its more an issue of wind resistance at 75 than the weight, only reason i say this is because my skid with no attachments is right at 10,000 plus any attachments that are on the trailer, and the trailer itself is probably 3k ish but I am not sure and my mileage is better with the skid
Thanks for the input
For anyone wondering my egts were fine, and sometimes it would hit 40 psi going up some of the hills (trying to maintain 75 mph), is 40 psi sustained ok?

Just got done towing my 5th wheel 13,700# 1,800 miles on level roads at 63 - 68 mph. Best I got was 10 mpg. I have the egr delete, Banks inner cooler, high rise and turbo back 5" exhaust. Not towing I get around 18 - 19 mpg. Sure would like to get 12 mpg towing it would make a big difference in how far I go.

2007 F-350 dually/diesel, Banks inter cooler, High rise intake and down tube, EGR delete, Turbo back 5" exhaust, Blue spring, 6.4 banjo bolts, coolant filter, Scan gauge II. Pulling a 40' tri axle 5th wheel toy hauler with a custom Harley in it. 70' overall .

I live in the Pacific NW and travel frequently through the Cascades, Sierra's, and the Central Rockies. I get 9-10 hand calculated pulling 9K 5'er with an additional 700 lbs of extras in the bed. Typical average speed going up, down or flat on the interstate is about 70 mph. Maybe a little less on the US two lanes. MPG goes up to 11 at that point. All stock at this point. But looking for tuner with out DPF delete.
