I'm not the type of guy that tracks MPG but just happen to flip through the trailer settings to see how many miles I have put on the trailer and the AVG MPG caught my eye.
13.4mpg...... That is an average over slightly more than 6000 miles of towing the current trailer. I live in the Phx valley area so all my camping is done up around 7500' and there are a few long hills to pull each way. I did just return from a 2400 mile trip to Montana and am a ***** on interstates and don't like to tow over 74 mph. so I did about 400 miles on I-15 just chugging along. rest of the trip was on back country roads (my preferred route when available).
Like I said, not a MPG weenie but it caught my eye. I thought it is pretty good.
A pic of my set up. Trailer comes in just about 7800lbs when loaded for a trip.
Something I just thought of. I've no clue how the mpg is calculated. the last leg of my last trip is about 90 miles and takes me from 7500' to about 1200' so it's mostly down hill. There are 2 6% grade hills each about 4 miles long.the rest is either flat or down hill. this may account for something even thought the AVG is over more than the 6000 miles towing that trailer.
With that kind of trailer, the biggest factors are pulling the box through the air at speed, and accelerating and decelerating the weight. Going uphill is usually cancelled out by going downhill, and vice-versa.
Your truck calculates MPG by monitoring a number of factors that it is aware of, primarily mass air flow and fuel delivery, then making it's best guess in calculations.
Your mileage is about the same as mine. For my 7000 lb TT I have traveled over 8500 miles averaging 13.2 mpg covering most of the eastern half of the US including most of the appalachian mountains. My best tank was 13.9 and the worst was 11.3 all were hand calcuated not the LIE-o-meter which I have calibrated to read correctly.
I hand calculate every time I fill up and put it all in a spreadsheet. I don’t trust the lie-o-meter… it’s off way more than it’s on point! I have even adjusted the AFE and that sort of helped but not enough to actually trust it.
I feel lucky to break 9.5 mpg. My bumper pull toy hauler has a GVWR of 12,800 lbs and is about 12.5' tall. Kind of like pulling a parachute behind the truck.

Not really.
For me, when I go up hill, I might be going as slow as 30 mph. Thinking my average speed is 60 mph, going up hill will take twice as long as me going down hill at 60 mph. There is nothing that is really cancelled out. Sure, you get better fuel economy going down hill, but for me, I am usually slightly on the throttle to maintain 60 mph which does not turn off the injectors.
95 F250/E4OD/2WD/5.8L w/Kenne-Bell supercharger/4.10/10k 5th wheel. I used to get around 5.5mpg. With some tuning, this summer, I got 7.0+ mpg.

Yeah on my recent trip from FL to CA I got anywhere between 9.57 to 12.06 mpg's averaging about 68 mph (hand calculated). My camper is only 6000 lbs and 10.5' tall, but flat on the front face, which is what drops the fuel mileage! Also, to be fair, it's really kind of all up hill when going from FL to CA! If I am driving 55mph I am usually getting closer to 13 mpg's or even a hair better.
I don't go over 70 MPH, even in Wyoming where it's 80 MPH. I'm kind of happy when the speed is only 65 or lower. MPG isn't linear as MPH increases, so going slower makes sense. But geez, I do want to get to my destination today!
I am similar. My rule of thumb is I will do the posted speed limit all the way to 65MPH. Once it goes beyond that I will creep up to about 68 mph and just set my cruise, regardless of how much faster the posted speed is. I stay I the far lane and only get over to pass people... most times though they usually become a chameleon and want to speed up when I am trying to pass them so I may have to step on it a little more to get around them. Sometimes they take off so I just get back in the lane behind them... often times I end up catching back up to them because they slow back down.. But yeah, I also know what you meant about wanting to just get there already!
I saw that…. And I was just sharing my experience….
I was just messing with ya....
I have a buddy that is always hand calculating every drop when we go on trips. He can't believe how good his mileage is nor does he catch on as to why I am always filling my generator gas can when I never run my generator Damn gassers are too easy to mess with
on this last trip I was in both Wyoming and Utah with 80mph limits. not me. I'm a right lane 72-74 max depending on what the truckers are doing. 64 is my comfort zone in Az where the speeds are less and the roads/drivers SUCK!!!!
