So what are folks average MPG when towing

[Can_t_Wait_Now]

Well I am towing a 2800lb base weight figure 3600 actual with full propane tanks Battery and gear, Towing with a 2011 Nissan pathfinder V6 Pa is hilly so in 4th gear allot is automatic but to limit beating the tranny I run it manual, Well I am getting 8.7 mpg. Not thrilled but oh well having fun anyway. We have a 600 mile trip to Myrtle beach planned so hoping no more than 4 fill ups one way.

I used to get 17 with our Fleetwood Bayside pop up behind our 4wd Pilot, but it was probably a bit heavier than your Sun Valley.

However, overall I'm much happier getting poorer mileage with my current setup. Tows easier, a lot more comfortable, longer camping season, far easier setup/teardown on travel days, more versatile, etc. We went with a pop up initially because we lacked a proper tow vehicle and a space to park a hard sided trailer. Once those issues were addressed, there was no looking back.

See signature for what I drive and pull o/w I'm getting 10-11.5 mpg and I never drive over 60mph even on hi ways that allow 70+.

I tend to get between 10 and 12, with an overall average of 11-11.5. I try to keep it to 65 but lots of climbing and descending is a fact of life where I live and that doesn't help things. I have a 2000 mile trip coming up in a couple of weeks and I'm interested in seeing what sort of mileage I'll get.

Two Trips so far with my setup. Getting a solid 11-11.5 on average. Mix of highway and moderate hills.

Regardless if I'm towing or not, or if I'm in one of the cars, I always track fuel mileage, at least enough to know what "normal" is for that vehicle. If the fuel mileage drops considerably without a understandable explanation, I know something has changed that needs attention.
That said, we get 11-12 mpg towing, depending on how well traffic is flowing.

Last 258 mi leg from Fernly to Redding, 9.17 mpg towing 10K. Speed 70 and less.

2013 VW Touareg Sport TDI with the small 18" rims, about #4100 of Palomino Gazelle in a 21 foot TT behind me, set up with an Equalizer hitch.

You can see what I get running empty, and when I am trailering here, for MPG's.
16.5 to 19.5 MPG's depending on which way the wind is blowing, head wind or tail wind. That's real world, not guess-o-meter in the dash.

A good example would be to look at the fuel logs in Sept of 2015 here, for trailering MPG's.
Fuelly.com for the 2013 VW Touareg TDI.

Using a stock 2013 Duramax with 3.73' pulling a 6000 pound rig I normally get 11-12mpg. On real bad days in nothing but curvy up hills I drop to 9mpg. In a head wind 9mpg. On straight flat with a tail wind 13mpg Nearly all my towing is done @ 65-70 mpg.

Well, I don't have a camper anymore since I bought a class A but I get 9.8mpg towing a 17' horse trailer with the class A. I just completed an 1800 mile trip and am showing 11.7mpg for the class A without a trailer. That is for a DP 35' long, 8.5'wide and weighing 22,500lbs (best guess as loaded for this trip) and the cruise set on 69mph. With my pickup (a 1991 F250 with 460cid) I only got 9mpg towing the horse trailer at 62mph and about 12.5 empty at 69mph. I am amazed at what that class A delivers. I am anxious to see what it does towing my new pickup but it should be about the same as pulling the horse trailer.

Just finished a long family vacation. '16 Ram 3500 Cummins, and a '15 Sabre fifth wheel, 38 feet long, somewhere around 11,900lbs, give or take a hundred.

Rapid City to West Yellowstone, MT - 11.1 mpg
West Yellowstone, MT to West Glacier, MT - 12.2 mpg
West Glacier, MT to Livingston, MT - 11.1mpg
Livingston, MT to Rapid City, SD - 11.2mpg

Day one could easily have been better, if not for a brutal headwind the last 100 miles. But, the last day could easily have been worse if not for a moderate tailwind; different route with lots of rolling hills.

TT and TV spec make the most difference. It's where I started. Right down to the hitch.

14-16/mpg pulling a 35' TT. Consistent with others in South Central US (climate more important than terrain; after spec), where both vehicles were highly similar.

It's double what my parents and grandparents got with their big block gassers, but same trailer brand.

[atreis]

11 mpg towing, 24 mpg not towing.

Depending on the size (heightxwidth, plus a small factor for the aerodynamics of the unit) you'll likely get somewhere between 9 and 11 with most trailers if towing with gas. (Exceptions due to large aerodynamic differences: AirStream, fiberglass eggs, etc... The V-shaped nose trailers are not significantly different.)

[bovellois]

13 mpg when I was towing commercially.
