We digress a little but you and KARNUT speak to one of my reasons for preferring my truck. My back is such that after an hour or more of driving the challenge of standing can take a lot of effort.  Getting out of a truck allows me to depart vertically!  

I'm in that boat with you. (back) As much as I love the cars ride the truck now is almost identical in that respect (after the suspension modifications) and as you note it's a vertical drop. Easy step up. I like the seat height as well. More like the sofa than sitting in a nicely padded five gallon bucket. 

 

That be as it may, mileage is still a matter of controlling your right foots urge and over riding you brains impulses. Easier done when comfortable.

Get your own tune that adjusts all parameters. The best thing i ever did. I averaged 17mpg with 6in lift on truck, towing a double axle trailer with a lot of household furniture from Texas to Fairbanks, Alaska through Canada.

If there was a way to get better gas mileage out of these trucks other than drive slower, the builders ( manufacturers) would do it. Soooo the obvious response would be if you don’t need one buy something that gets better gas mileage, right? I drove a truck daily for 40 years for work, nice ones I’m a business owner. My wife drove a car. Can’t imagine why a person would daily drive a truck that didn’t need to.

My daily driver is a Truck and technically I don't need one. What I do need however is 4 wheel drive. It's either spend 35k to 45k on an SUV or spend 35k to 45k on a pick up. At that point, it's all about looks for me.

I drive quite a bit and honestly 19 mpg is pretty good... I've had two GM trucks, old truck was a 2014 double cab 1500 4x4 3.42 V6 with highway tires new truck is a double cab 1500 4x4 3.42 V8, deleted front air dam  with slightly up sized cooper atw all terrain tires... I get about 19-20 mpg on rural roads/ high way, more like 17 in town with my new truck and that is all I ever really got with my old truck.... I had a buddy who drove like grandma with a cup of hot soup on his lap, always slow from the red lights etc, who had the same exact spec truck as I did, I drive slightly aggressive compared to most, I accelerate quickly etc... he and I got the same MPG outta our trucks... Your moving a heavy machine with a 5.3L V8, 19 mpg is pretty darn good... I always tell people if you're watching the MPG #'s on your truck you probably can't afford to be driving it...

Going to neutral while moving is never a good idea. You could accidentally go to reverse, you could need to suddenly accelerate. I can picture someone panicking flooring the gas while they’re going back in drive not pretty. Not to mention scrubbing speed braking instead of engine braking not efficient.

You can bump the selector into N and back into D.  In order to shift to R (from N/D), you have to pull the handle towards you and then move it into R.

Engine braking is a closed throttle situation. It using less fuel. Your mileage display is not properly calculating the effect of coasting in neutral.

A moose runs out and you have to swerve and accelerate to avoid it. Your brakes suddenly overheat, fade and give out and there’s cars stopped at the bottom of the hill. You see a tractor trailer approaching you from behind rapidly, lights flashing and horn going clearly about to hit you and unable to stop.

I wasn't going off of the computer, all paper math.

 

The only moose that I have ever seen in CA are in zoos.  Antelope Valley is all high desert, +/-2300' altitude.  The only things that dart out in front of moving vehicles are squirrels, coyotes, rabbits, and snakes.

If i see a moose on the road in socal, I’m driving straight to the ER.

I can picture in my mind a N cruiser approaching a intersection where the approaching traffic has to stop. As the N coasting driver enters the intersection out of the corner of his eye he sees the other driver didn’t stop. He mashes the gas, oh oh.

Wow, that was a good drive!  I'm old enough to have driven the Alaska Hwy before it was paved.  It was a beautiful drive then but driving hundreds of miles of gravel can do wonders to a paint job!

Pessimist much?

 

No intersections on any of the hills/mountains that I roll in N.  Besides, if that were the case, your cruiser was doing it wrong.

Decel tables on new stuff shuts off the fuel on coast down. N is not required. Uses more fuel and in most states is illegal. Why? Because the majority KNOW its dangerous.  California Section 21710:

The driver of a motor vehicle when traveling on down grade upon any highway shall not coast with the gears of such vehicle in neutral.

I do that. Lately, it seems, lots of other people do too. I read the other week that the number one selling vehicle to people making over $150,000 per year was the F150.

Well, I wish I made 150k a year. I'm just a firefighter who makes a little over 80k.

Me too. I spend the kind of money on my truck that would get me a lecture from lots of people here. 

 

I'm just saying you don't need to be a worker using the capabilities of your truck to buy one anymore. Down here in Austin, it seems like every other vehicle is a full-sized pickup, and EVERY car is foreign. :>(

Last summer cruising in the Banff National Park In Alberta at 111KM/H (69MPH) I averaged 6.5L/100KM (36.2MPG) over 10000KM (6200 Miles). This year on major highways at 125KM/H (78MPH) I'm averaging 8.7L/100KM (27MPG) I mainly drive highways only about 15% city driving. I have a Borla catback from my Dealer and tow mirrors, 3.42 rear end and 18 inch wheels. I typically use cruise on the highway and now have 64000KM on the odo. However when using Autotrac or 4wd my mileage jumps to 16.4L/100km (14.4MPG). Overall I love my truck and will keep it forever, may buy a car for the summers as I miss having a manual transmission.

IMG_6919.jpg

What engine? what cab, what box, what gearing, what trans?

 I struggled to maintain 10-11L/100km when my truck was stock around 100-110km/h with cruise or manual intervention. '16 crew cab short box LT z71, 5.3L with 3.43gearing bone stock 6 speed

 

Also, that 6.5L/100km is only for a certain mileage (the largest history being 650km). I understand you may have maintained that during the whole trip but I find it hard to believe.

 

Personally I think I can drive better and smarter than cruise can, therefore you can actually save gas if you have the patience and control.

Is that true? That’s an interesting statistic.

      Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.
