On my 1st trip pulling anything with my new (new to me) truck to Lake Fork, I got 13.7MPG. 3/4 highway doing 65-70 mphish and the rest 2 lane back roads. 

Towed about 2500 lbs boat and trailer, bed loaded down, and 4 adults. Smooth ride, picks up and slows down with ease! We rented a cabin on the lake with a private boat ramp that was pretty steep, the 1st attempt I was too far over and had to come all the way out to get strait but the rears kept breaking lose because of some gravel so I put it in 4X4, no spin at all came right out.

TRIM: LT Z71

MOTOR: 5.3L (no mods)

Sorry no pics, I'll update with pics on my next haul trip. 

 

My first tow with the '19.  It doesn't get great mileage to begin with (about 15mpg) but I towed an 1800lb utility trailer about 500 miles into Kansas and back (relatively flat) and netted a whopping 9.9mpg.  I used the haul mode one way just to see how it ran.  I was very surprised how poor the mileage was.  I didn't buy it for mileage but sheesh I had an 8.1L 2500hd that did better and towed like a dream.  The real kicker is the small gas tank.  With 24 gallons at sub 10 mpg I'm looking for a gas station at 180-190 miles, and I had to stretch that in Kansas to about 220 miles which became very white knuckle.    I'm hauling a car on the same route (about 6k total) next week any takers on how bad that's going to be?

Empty the trailer is 1500 lb, guessing another 1000-1200 lbs of firewood

2019 6.2 4x4 NHT with 33s.  I do great unloaded.  Can average over 20 if I keep it under 70.  But with my 6000lb camper I only get about 8.  It pulls like a dream but I could get 10mpg with my old 2014 5.3 z71.   Maybe it will get better as i get more miles on it.  I've done as bad as 7 in high winds.  Wind is the killer with these rvs.  I think it's worse than the weight.

Ezekiel2517  above is correct when he says this.   A high profile travel trailer or any trailer being towed that sticks up above the cab is basically a giant wind brake - it kills your mpg.

 

 

Last October ,  We did a 2000  mile round trip  from Colorado to Texas to pick up our new lance travel trailer.

Truck:  2019 Sierra 1500 AT4   6.2L  - 10 Speed transmission  w/ 18'' Goodyear Duratracks.   Stock Air filter & Exhaust

Trailer:   2019 Lance 1985 Travel Trailer  19'  trailer - tow weight   on return trip was right @ 5000lb

 

Trip out (no trailer)  :  mileage average between  17- 20 mpg  @ 75mph - 80mph

Return Trip:

     (a) Day 1 - Heavy  cross winds/head winds (gusting to 30mph) :   5- 7mpg    @ 70mph

     (b) Day 2 -   8 mpg  @ 70mph less wind /   at end of Day we dropped to 50 -  60 mph (due to road traffic)  and got 10mpg

Weight is a factor when accelerating and when climbing.

 

Aero (frontal area, and wind) is the factor all the time -- and this THE factor when on level cruise.

Aero is also the reason speed is a big factor.
