I dunno how the hell you guys are getting good mileage towing... just towed my 7800lb GWVR 33ft camper with my 2018 3.5EB HDPP and averaged 9... and that was on premium! Speeds were mostly 65-70mph. When I slow down to 55-60 I can get around 11.
You answered your own question. Your pulling a huge parachute, the faster you drive, the more it drags you down.
Sacramento to 20 miles northeast of Truckee ca w 6k rv trailer at 60 to 62 mph 9.3 mpg total both ways same tank of 89 octane fuel. loaded for 6 days in the woods. sea level to 7300 feet in 85 miles. total trip approx 250 miles total. pulling machine!
That camper in SweetLou's photo looks like the front is up higher than the rear. Properly hitched with a WDH, the front should be slightly lower. Makes a big difference. also, slow down ! What's the hurry ? It's a vacation. Chill. I drive 54 mph with tow/haul and cruise when towing my 7500+ pound TT and just let the 3.5 EcoBeast do it's magic. 87 octane.

1) I thought the front was higher too. It’s actually perfectly level. Also I hit the scales and confirmed exactly 1000lb tongue weight (before WDH) which is about 14% tongue weight.
2) I don’t disagree, but with two small kids, the sooner I get there the better!!
Did another 650 miles with the 7500lb TT. Averaged 8.3 over entire trip. Speeds averaged 55-75 depending on conditions. Ran mostly premium (holy shnikees is it expensive to fill up on premium!)
On the trip out I found the EB maintaining 9th gear on the flats so I only locked out 10. On the trip back I locked out 9 and 10 and found the truck stayed in 8 almost exclusively (even when climbing modest grades) and made for an overall much more enjoyable ride. I also averaged better mpg (7.8 on way out, 8.3 overall by the time I got home) with similar speeds and trip times. Power was plentiful as always.
Next trip in two weeks. I’ll experiment with turning off the sway control. Rumors are here that turning it off increases mpg. I am definitely locking out 9/10 from here on out.
I habe 3.73 rear end FYI. I’m sure with 3.55 you might be slightly different results.
I was wondering (I ordered a 2019) what gear I will tow in with the new 10 speed. Probably 7 or 8?
7th gear is a 1:1, 8th, 9th and 10th are overdrives. So, depending on your new truck's axle gearing, I'd say, probably both 7th and 8th with maybe 9th if you have a tailwind. As you can verify, it's always better to lock out any taller/higher gears you don't use.
