And that is exactly the range for our Tundra. It is the EB that has a much higher deduction (maybe close to 50%) and that may have consequences—perhaps excessive engine wear. Time will tell. Anybody to 100,000 miles with an EB?

I re-checked my gas mileage this morning on my way to work. Short commute of about 15 miles highway. I reset my fuel economy estimator when I got on the highway and I checked my results when I came to first stop light after exiting the highway. 27.9 mpg at 55mph. I looked at a topo map and start elevation is about 541' and end elevation is 550', essentially flat. Light winds.

The gauge referred to is generally "off" by a percentage factor. At that speed mine would be reading high by about 3/4-gl. That is the same mileage my 8,000-lb truck does at that speed, so my "actual" would be right at 27.

This gauge type IS quite an aid -- once one knows the correction -- in seeing the effects of different speeds, different gears, changing winds, etc. Quite useful, in fact, for spot checking.

And it's an eye-opener to see how fast MPG drops when one is just sitting/idling. Takes many miles to achieve the highest MPG, and then all is lost in 15-20/minutes of idling over the course of a day.

As Average MPH also drops one is more aware of the relation between the two averages, of speed and fuel consumption (use Engine Hour function which may be connected to Odometer operation).

Still, it really blows me away that a big ol' pickemup can get the kind of mileage we all once associated with crackerbox Japanese cars.

Gene,
Just out of curiosity, what does your tongue weight usually come in at? It seems to me that is perhaps a bigger question for most of the people considering a F150EB / Tundra / Chevy / Dodge, etc. 1/2 ton trucks, rather than can the EcoBoost pull the weight, as overloading the truck's rear axle is a recipe for disaster. I've read in the forums where one user went out and purchased a F150EB with the max tow package only to take his 25FB loaded to the scales to find out that he was over the truck's limits. Yet other users seem to do just fine. I know from reading your other posts in the forums that you are a big believer in not exceeding the manufacturers specs. So I was just curious as to where your 25FB and Tundra came in at and how much safety margin do you leave yourself and reserve cargo capacity do you have left?
Cheers,
Rion

Rion, if you can find a link to the referenced post it would be helpful to review. The tongue weight of the FC 25 FB is 837 and the 25 SS is 835, I towed a 25 SS with my EB and was never close to overloaded. I tow a 28 and still not overloaded. The 28 is has a Tongue weight of 976 mine Sherline scale tell me mine is at 840 with a Hensley in place. I keep my tanks M/T most of the time. I have not made it to a Cat Scale, I think that I need to do check out the trailer at a Cat Scale to be sure I am not living in a dream world.

Rion,

I've never weighed the tongue. To figure out what we could do with this setup, I used a bunch of guesses and weighed many items on a bathroom scale when we bought the trailer.

I took whatever Airstream said was the tongue weight, added for spare tire and propane and then some more because Airstream underreports some times. I figured out just about how much we would take in the trailer, weighing clothes, food, etc., and then adding several hundred pounds to see we would come up pretty far below gross wt. for the trailer. A history of backpacking helps you think light when traveling.

I figured the payload by taking the Toyota numbers, subtracting options (tonneau, running boards), our weight and weights of stuff we take and tongue wt. adjusted for wt. distributing hitch. We came very close to payload.

Everything looked fine. This was more than 5 years ago, so I can't remember all the figuring, but I was satisfied. There are no scales within 50 or more miles of where we live (I looked—the last one closed years ago), and by the time we are on the road, I want to get somewhere and not look for a scale. So I've relied on the estimates, guesses, and things weighed. My experience with 6 Toyotas is they are overbuilt, so being right up against payload doesn't bother me. If you get within payload and use a weight distributing hitch properly, you should be fine on the axles.

I know many say you have to go to a scale, but there's plenty of information available (some by weighing what you take) and you can figure it without leaving your house. Put as much weight as possible between the truck axles and balance from right to left in both vehicles.

Gene is right on the money, I also have a hard time getting to scales. I have a Sherline Scale (Load Cell) which helps to get an idea of what is going on. I also tow a boat long distance using a different hitch so the Sherline was a good investment for me. The bathroom scale method works fine and you can pick up scales at garage sales cheap if you don't want to you your home scale.

The CAT Scale Locator allows one to find certified, three-segment scales clear across the continent.

1,450 of them. If you've ever travelled the Interstate you've passed a half-dozen per day.

It just doesn't take that long to get a set of weights, or to do a few adjustments.

Verification is the name of the game.

There appear to be Rv'ers who'd rather buy a far more expensive to buy and expensive to operate TV than whom would take the time to set up a better-suited TV. That 90% of rigs are incorrectly-hitched is inexcusable. It includes everyone who hasn't done the verification.

Braking, steering, fuel economy, vehicle longevity, tire & brake life, etc, all depend on those last little bits of adjustment. (Pays cash money, IOW).

Lots of scales, but I trust my calculations.

It's what most say -- in so many words. I still find it hard to believe (as the difference when it matters is what is at stake).

You all ever come this way and I'll do it for you.

Hey, F-150 and 1500 owners - open the door jam and read your max payload capacity. On my F-150 EcoBoost it was 1209lbs. So much for Fords tow guide and it's use. Expensive lesson.

That being said, if you can live with the max capacity, the 2013 F-150 Crew Cab with the new Sony Synch Nav/Stereo, ride, handling, seats and that wonderful EcoBoost engine are great!

Yea - expensive lesson indeed, and that's all I'm gonna say....

Ohh? What is the FAWR and the RAWR? That's what is worth paying attention to if there is room past "payload". And the way things were done on cars pulling these trailers back a few decades (and today, with smartest hitch rigging). Hit the scales and spread out that TW.

So - let's be gratuitous and say your max payload is 1330lbs...

Subtract 840 for tongue
490 pounds
Subtract 200 for topper
290 pounds
One driver with clothes on 210 pounds
80 pounds till max
And one passenger with clothes 130 pounds
BOOM - 50 pounds over max capacity....

Your Max capacity can be found on drivers side door jam - bet ya it's more like 1209lbs...

And that's assuming you have both axels used under their max capacity and you are not exceeding you OEM rims or tires...
