Hummingbird Gas Mileage question

We are pulling a 2018 HB 17FD with a 2016 Silverado 4.3 ecotech and according to the Silverado computer I'm getting 17.5 MPG while towing, 24.5 highway MPG solo and 19 MPG combined for the last trip of about 400 miles. Before I get really happy about the mileage I was wondering what other people were getting for mileage with like equipment. We downsized from a Fleetwood 25' class A that got 8-9 so you can see why I'm happy. Thanks for your input!!

We have the same trailer. Just switched from a 2015 Highlander XLE to a 2016 F-150 XLT Super Crew with ecoboost. Got home yesterday, round trip of about 1200 miles, with a bit of no trailer driving, from Spokane, WA to Tofino, Vancouver Island, BC. 12.5 mpg at about 65 when possible, occasionally faster and often slower. Some steep and windy roads on Vancouver Island, with some 18% grades that were, thankfully, short.

Thank you for the response Bradley and Rachel. Your response gives me something to compare to. We have a 2600 mile trip coming up. MPG isn't super important but I was just curious how I compared to other people towing the same trailer. Thank you very much.

We have the basically the same truck but 2015 with the same engine and a hummingbird 17RK, it was exactly what you posted.

87 Yugo, thanks for your input. I'm really happy with pairing the Silverado to the Hummingbird. I do use a Husky WD hitch and the bird pulls effortlessly.

My numbers are pretty much the same, slightly higher, as yours towing my Hummingbird 17BH with a 2018 Colorado. I guess physics is real and it takes the same amount of fuel to overcome the wind resistance of the trailer no matter what you are towing.

We are pulling our 2018 HB 17FD with a 2013 Silverado 5.3L Vortec (Z71, 3.42 ratio, flexfuel). When pulling the HB I get about 11/12MPG, without pulling I get about 18/19MPG. I am pretty sure the mileage is bad because of the "geared down" rear end. The truck is capable of towing up to 10,000LBS and our HB is only 3,600LBS loaded, definitely overkill (unless I get a bigger TT)
Sounds like your doing pretty good with your 2016 Silverado Ecotech!
Happy and safe camping

Thank you for the response. I've been really happy with the combination of truck and trailer. My max towing with the 4.3 is 6,000 #s so you would win on a larger trailer but for the Hummingbird this works out well.

I get 10 mpg in my Greyhawk 31fs at 65 mph. But when I tow my 25ft 5,000 lbs race car trailer it drops to 8 mpg. Guess I need to get me one of those new eco-boost motors....

I think you're getting pretty good mileage.

I have a 2018 Ford 2.7 eco boost and get about 25 mpg highway, 19 around town and about 12.5 mpg when towing a 17RK. Pretty much just like the other 150s.
