not really all that surprising given reports that the whole package power and tow ratings are underrated due to cooling package issues.. so given proper conditions it can tow way past its current placard ..Tows me 28ft camper just fine. Got 13 mpg doing it too, that's what my tundra got empty.
I'm not happy at all with the fuel mileage from this Truck.
Background: I had a 2015 Ram Ecodiesel over the past 3 years. I purchased it primarily to pull a Toyhauler for my HD Ultra, now Yamaha V-star 1300 Deluxe. My avg fuel mileage logged over 8000 miles was between 15.5 - 17 mpg. I would still be driving the truck except for all the issues FCA has with the power train. I had an engine fire the year after purchase (used) @ 45000 miles while pulling a 4000 lb RV. 30 days later I get the truck back. FCA also retuned the engine due to EPA lawsuit that detuned the engine bad. I was able to find an aftermarket tune which restored the power and fuel economy it had prior. This summer in Reno NV the 8 spd tranny went out. After I got back I decided I had enough and leased a new Texas Edition 2lt 4x2 truck. I am pulling the same Forest River 22RR toyhauler @ 5700 lb loaded that I towed with my old Dodge. The worst mileage ever was 13.5 and that was my fault for leaving it in cruise control pulling hills. My return trip avg 15.5. My trip to Reno NV netted me 17mpg from Abilene.
So far I have towed the same trailer with the new Silverado twice ( 500 mile round and 450 round) covering the same roads that I pulled with the Ram. My best mileage so far is 13.8, my lowest is 11.3.
So how is it that the competition with a 5 year old truck with engine issues out performs the brand new shiny chevy diesel with more power and more gears? I purchased the vehicle for towing and expected at least the same mileage or better than the RAM. If Chevrolet can't fix this issue then it's back to driving a 2020 RAM Ecodiesel with the new motor.
Is that 7,000 lbs dry? or loaded? I am thinking about getting a 2020 GMC Sierra Denali, crew cab, 4x4, and concerned pulling a 7-7500 lb travel trailer across the country will suck since im getting close to the max towing capacity of 9k.I pull a 27 ft bumper pull RV. 7,000 lbs, 4,000 mile trip.. 14 mpg with tail winds. 12 mpg with no wind or slight head winds. 11 mpg with stout head wind. Seamed effortless most of the time.
My Tundra got 8-10 mpg at 62 mph, with lots of straining and high rpms on hills.
2020 LT, 3.0 LM2, double cab, fiberglass shell on bed, 4x4, 275x60R/20 at 49 psi.
Are any of you towing a camper with your LM2? If so, what kind of camper and what are you getting for mileage??
Coming from a very nice and 2016 Silverado 4x4 with a 6 speed transmission tune by me with hp tunners... I am not very impress with the fuel mileage on the our new LM2 denali 4x4 (while towing) since it doing just a bit better than the old truck; but I do realize that there is a untap hidden potential and in it's bone stock form with the new 10 speed transmission it seems to perform far better when towing.Are any of you towing a camper with your LM2? If so, what kind of camper and what are you getting for mileage??
I’d move to a different truck with a 37ft trailer.I’m towing a large (37’) tt. Getting 11 mpg on my LT short bed. Right up real close to GCWR. Concerned that I may need a bigger truck. Got E rated tires and timbres SES. Using a Hensley hitch so there’s no sway, BUT you KNOW that trailer is back there. Any thoughts on this? Would Airbags make a difference? Truck hasn’t struggled to tow or stop in normal situations. It’s not a rocketship, but it’s not a dog either. Thoughts on this? Thinking if I keep it to do a Banks Derringer a Titan fuel tank (if and when they become available) and maybe airbags? Wondering about the 3.23 rear and if that’s a problem. What benefit to move to 3.42 or 3.73?
