I am always asked what MPGs does my dually get.
I tell them I don't really know. I did not buy it for economy. I bought it to do a job. Tow my Momentum. whatever it takes in fuel to do it is what it takes.
The follow up qustion is usually:"Well what does it get not towing?
I tell them, I don't know, as that doesn't happen often enough to track it.

You drive the speed and style that you drive and unless you’re already drivin miss daisy, you drive slower if you want to use less fuel. And you drive faster if you don’t care and want to get there sooner.


Because you want to know if driving miss daisy is saving you enough money to make the extra time, aggravation, and road rage incidents worth it. If it's only saving you $10/month, stomp on the skinny pedal and keep up with traffic.

Haha, thought of this post as a passed multiple people doing 25-30mph on 35-40mph streets this morning.

What really burns my arse is when I come over a hill with 115,000 lbs in tow to find a flipping Tesla putzing along at 80 kph in the slow lane on a busy 110 kph highway. What do you do? There's people doing 125 in the fast lane so getting over to the left is not going to work; Could slam on the brakes and burn three weeks wages off the brake linings and another days wages of diesel lugging the load back up the hill trying to get back to speed if you ever get a chance to get around the pesky savior of mother earth. I could just come flying up behind the cursed Tesla with the air horn blaring knowing full well it is capable of hitting 80 mph in about 1/2 of second. I could pass her on the right hand shoulder and hopefully teach her a lesson. I guess I should be more sympathetic ... after all she needs to make it from Edmonton to Calgary on one a single charge so she's only doing what she's got to do.

My truck is my daily driver so fuel economy is a bit high on my priority list. Having said that back in in '12 it was clear that I wanted a truck that was equipped with DEF because I new it would yield better fuel economy. With 270k miles on my truck, those fuel savings adds up which means more money stayed in my pocket.

This seems pretty reasonable to me. I’ve bumped up my towing speed as the trade off of MPG vs MPH is worth it for me after I calculated it.

Best test that total emergency stopping distance.

And highest maneuvering speed prior to rollover.

A pickup pulling a square box trailer with slide-outs is one atrocious rig when it matters.

Reasonable highway speed won’t be above 65-MPH just for typical electric drums.

Or above 55 with a prayer of an emergency swerve.

What’s the lowest legal speed on that road? A “pennies-per-mile” defense ain’t gonna cut it morally. Could be someone ill or injured, or with a poorly functioning vehicle, but making best headway.

Or one rounds the bend and there’s a school bus full of children and nuns over on its side.

“Why” they’re traveling slower, yet legally isn’t any of my business. Only shows I’m a poor driver it bugs me.

In USA, it’s illegal to block entry to passing lane. No inherent ROW. (That’s where I’m going). One backs off to get a pass over soonest (also law), so that lane is “clear”. It’s the only choice should worst situation occur. Literally why we built with two lanes nationwide.

There is not any such thing as, “the fast lane”.

Left lane tailgaters are equivalent of being without insurance. SHOULDN’T BE PRESENT. (They win the Darwin Award). Faster travel speed = zero ROW. 200’ spacing or better at all times (more for big trucks), and not ever in left lane till vehicle ahead has finished pass.

Heavy traffic means one travels more slowly. Upper limit isn’t the thing. ROAD CHOICE determined travel time, not travel speed.

Todays car drivers are worse than they’ve ever been. Think metro freeway and rural Interstate are the same. They aren’t.

Per radar the average they cut in front of my rig is 80-ft. Should be 200+ and still solidly accelerating away. (Need 700+ feet to stop)

Don’t cut in front of big truck without 7-8 lane stripes visible, minimum. Merging on-road the same. Running up ahead of me going into construction and not ten feet from car in front. Etc.

I agree about the selfishness/stupidity which merge into one-ness above 45-MPH. But legal travel speed in correct lane isn’t one of the highway problems. (I slow to 50-45/MPH at exits BEFORE the ramp as that’s the ONLY prudent way to exit per road design and vehicle physics).

My rig WILL come to a full, controlled stop UPRIGHT. God help the stupid/selfish as law doesn’t require us to sacrifice ourselves. Left lane is only way to avoid smashing the TRAVEL LANE problem. It’s the SINGLE choice. Left lane is passing only (not overtaking), and for EMERGENCY use.

Anticipate that’s always just ahead where it can’t be seen. CYA. Then can use the designated lane to get past without qualms. (Where the stupid & selfish wind up is between them and their god).

This is a central fact of how things are.

Luckily, the stupids are predictable. Travel in packs. It’s no feat to slow a bit till they’re far away. I do it all day. Doesn’t change my trip plan. Travel speed adjusted to traffic volume & other conditions. Etc. You know the drill: Maximum Vehicle Separation the day long.

It’s also congruent with fuel economy: least use of throttle & brakes. (Next to no passing, not even several times per hour in most cases).

And aren’t you guys using LADD channels to warn each other? AM-19 on CB ain’t what it used to be , but it’s still operative about rolling or stationary hazards.

Curious on how much diesel is in your area Fish. It's $6.25+ and going to the moon where I live. Electricity is not any better. .38 cents/ KWH at the lowest and going up too. My wifes car takes all night to charge so I have to charge a lot at super high 3rd tier rates. It's now a wash or even cheaper to put gas in it.

I live in Kalifornia. Please send money.
