I think it’s them Florida roads. I had a Hyundai rental car there last year and suburban driving got 65mpg with a gas non-hybrid car. Blew my mind. Those Roads are perfectly flat and at basically sea level so I think that helps mpg a lot. I sure ain’t getting 22 over here in PA with all these hills

Its flat hear..

After some research, I may not do this now. The trade in on my truck is $45,000.

The sticker was 79,000.

I refuse to take such a hit.

This fiasco dropped the value on 6.2s huge.

I'll keep it for now.

Sad thing is my truck runs just fine with 48,000 miles. What are the chances now. Most of these grenade early on.

It’s the market correcting itself. You bought high and now pricing is coming back down.

isn’t the 6.2 in a 23 recalled? I don’t know tye details but I thought they year was included.

There's always the AFM delete cam kit option.

Just drive it and DGAF. It's either going to break or it ain't. Odds are in your favor that it ain't.

Yes.

Thats part of the reason the value dropped so much overnight.

I have a 23 High Country 6.2 with 48.000 miles and with all the failed lifter talk and now the big recall, I think I'm ready to walk and get a 6.6 gas.

Diesel is not for me. Used to be a long time ago though.

Probably looking at an LTZ with the LTZ premium package. Not much difference between that and a HC.

I do tow a cargo trailer and a 25 ft travel trailer so the 2500 would be beneficial but I also plan to daily it.

Mpg isn't a big deal to me either.

Talk me into doing this. Or talk me out of it.

3.0 is a completely different animal from the the 6.6

I've got more years running 04.5 LLY, '10 LMM , '11 LML, and '18 L5P than I do running '21 LM2 and '23 LZO

If fuel economy matters, ( I realize you said it doesn't) with them doing the same jobs (mostly daily driver, but some towing) the L5P ran high '17's and the '23 is giving 29.1 'life of vehicle' (30,000 miles so far)'

For me, the bigger bed is worth it. I could not imagine going back to a half ton short bed.

Are you running a 2500 or a 1500 with a standard bed or ...?

I run crew cab standard box (6'8") 1500's. (3 one so far)

Double cab 1500's are also standard box. (I tried one, but probably won't run another)

I also can't see myself in a shortbox truck.

Totally worth it! I have a 2024 LTZ that has every option that the High Country has with the exception of the stiching on the seats and power step bars. It is a crew cab with an 8ft long bed, and IS a pain to park in most parking lots, however, the surround cameras make it a LOT easier AND I can go to Lowe's or Home Depot, put a load of 8ft lumber in and still shut the tailgate. It is hands down an amazing vehicle. It is a bit rough riding unloaded and I currently daily drive mine and get about 14mpg in town, best of 22mpg when I take the interstate.

What octane fuel are you using and is it ethanol free or if not do you know how much ethanol it contains. I haven't really been thinking about it that much as per the ethanol content of the fuel I am getting as I really have no control over what my retailer hauls me ( I farm ) as they don't handle anything other than regular fuel and there is no choice to go non ethanol. Its been a few years now for sure that they started in with the ethanol theme as before that it was all non ethanol fuel my retailer handled for farm use. The only fuel I am aware of that might not have any ethanol in it around here in Alberta is premium fuel and no 100% guarantee it won't either to be honest and its stupid expensive as we get so ripped off with fuel prices here compared to most of the states and yet we are sitting on the fuel. But anyway ethanol content vs none would certainly make a difference to fuel economy, as well as the other factors such as wind, lay of the land and elevation and of course ground speed and other items like tire pressures, tire type, weight being carried etc.

One of these days I should make an app ( like I know anything about computers LOL ) where it tells how to choose each route so its all down hill with a tail wind going too or from said destination. My instant fuel mileage shows I am using zero gallons per mile when going down hill with my foot off the accelerator, that's as far as I have gotten with my fantastic idea

The energy difference between 10% ethanol and 0% ethanol is 3%. 10% is the maximum and it is often less than that. I highly doubt you would ever notice the difference.

Definitely one would have to do a lot of accurate mileage testing to crack that nut for sure, based on the 3% difference in energy it would equate to around a half a mile to the gallon for example with a truck like mine.

I normally use a mix of 87 and 92, depending on which I feel like buying at the time. I haven't really seen a difference between the 2. I am not sure what the ethanol content is as I usually only worry about that with the lawn mower and atv's. My "normal" gas mileage is around 14 with stop and go traffic, I can get into the 20's (22 showing as best) when on longer highway and interstate trips. I don't get on the gas leaving stop signs or red lights, and I don't idle a lot.

Hear in upper Minnesota, it/87 octane gas, can be 10-15% ethanol, but law, limits it to 10% in the winter time.

Last year when getting the pickup from new i did multiple experiments, as well as multiple tanks, on different fuels just for the heck of it.

Summer fuel only. For less argument, im not posting miles per gallon just my gain. Starting from normal 10-15% ethanol 87 octane at the pump. Trying 91, not sure if its ethanol free or not, i gained 1mpg per tank/s solid, not worth the extra .50 cents more a gallon. Finding non ethanol 87 octane not far from hear, multiple tanks gained a solid 1.5-2 mpg. Cost changes, some times, lower some times more than another station with only ethanol.

Wile spending a month last winter in New Mexico, in that area it was 86 then 88 then 91 at the pump choices, the lower 2 had ethanol. Going 88 from the 86 was a solid .75 cents more a gallon. I did try the 86, it ran fine, no noticeable difference, but i lost a solid 1mpg per tank from 87 ethanol.

21-24.

And 6.2s have been on the down trend at the wholesale auctions prior to the recall due to them locking up in the first place. Even the 5.3s had dropped for some time but those have stabilized. 6.2 on the other hand keeps dropping due to the recall now.
