My gas engine hauls my 7000 lb trailer up mountain passes at over 10,000 feet while staying at the speed limit and passing semis...I know that's not a really big load but that is why I don't need a diesel and didn't waste money buying one.

I had a Cummins diesel in my old 2008 Dodge 2500. Now I have a 2019 6.2L gas engine. Interestingly, the hp and torque ratings of the old Cummins were very close to the new gas engine. Given, I had no issues towing my 8K TT up any of the passes here in Colorado, I'm sure my new gas engine will be more than satisfactory and save me tons of money over the purchase price and maintenance costs if I had gotten the Diesel.

To imadentguy... yep, that's about right. Sounds harsh, don't mean to be, should'a bought the diesel. I'm at 16-17MPG unloaded, 11.5 pulling 10k. No gas engine is going to have the torque needed to get the load moving, or the HP to keep it moving. You'll be dropping into lower gears while I'm just watching the boost gauge approach 25 pounds.
I had a gas SuperDuty. The darn thing would scream climbing hills, and when fully loaded semi's are passing up a grade and I climbed the slow vehicle lane at 20 under the limit, there was no way I'd ever have another. The ugly truth, SD gas is for hauling groceries and cruising around town, diesel is for working, and hauling loads.
To acadianbob... Amazon delivered the Hellwig BigWig a few days back, It's not on yet. Do you have a factory bar retrofitted/installed or aftermarket?
LOL first i want you to know you have your opinion and like wise i have mine. So were not going to start urinating all over everything, and i am in no way shape or form knocking you. I am just adding my .10. Everyone that considers these things think they need a diesel. Pretty sure about 95% of individuals driving 4x4 diesel ford superduties are rolling around in a 60 thousand dollar plus grocery getter that they cruise around town in. At least down here in south texas that seems to be the norm. I dont know man. I am a maximizer and i over research every high priced commodity i ever consider purchasing. I was truely torn pre purchase, but i know i made a sound decision. If you are an average consumer with an average income, towing average loads, it just dosent make sense to me to try and pay for a diesel. Are they bad ***? Yep... are they powerful? Oh yeah......problem is, when something goes south on that bad boy and you have no warranty coverage does the average consumer have to LITERALLY re-fi the house to fix it? Hope your sitting in the green BOYS. Got plenty of buddies that drive/ have driven diesels. They bought them once, they broke, they bought gas. Diesel trucks only make sense if you are either A. Loaded and it dosent matter B. Towing a 10k lb plus load regularly or C. If that whistlin’’ rig is making you money every time you start it up. My truck tows just fine. Does it down shift and spin? Yep thats what its designed to do. Put in on tha’ floor an’ let er’ eat! Was i in the right lane with the big rigs running slower than traffic? Yep i had a load in the mountains. It was the safe and responible thing to do. Does it love gas? Oh yeah..... just filled up this morning in houston. $1.87 a gallon. Diesel? $2.73. Im out right there. For my use financially it dosent make sense. The fuel mileage towing sucks but for the number of times a year i will tow with it i can live with it. Diesel makes towing ALOT easier, i will not disagree with that at all...... but grocery getter? Come on man. My 6.2 is an animal and it gets the same mileage as my friends silverado 1500’s, difference is i can actualy do something with it. Every superduty truck is a platform built to work. Some just work easier than others, but at an absurdly inflated cost. The diesel is easier to tow with without a doubt... but grocery getter? Please tell me you are not one of the guys white knuckling a 14k lb. Montana doing 5 over through the passes just cause’ you can. Yall be safe and be courteous..... and if you will excuse me i am now going to take my f-250 gasser to krogers to pick up some eggs and some beer. :-)

Imadentguy - and your point is? Your narrative could have gone on for pages, and, I still would have bought a diesel, BECAUSE, that's what I WANTED! If everything I bought had to make financial sense............If ya gotta worry about what it costs, ya can't afford it - LOL

Agree with ATC Crazy and jbrnigan. Just following the door sticker works if you are towing at max capacity. If you aren't, lower your pressure. There's no correct pressure for all conditions, and the door sticker is incorrect if you're empty. It's not rocket science.

55/50 when empty, add air pressure when towing.

Hmmm aiiight then.......inspired by this thread, and because its been a while since i have done it, i aired my tires up to factory recommended pressure of 60F and 70R today at work, and the ride quality change was dramatic. I feel like the the truck holds a line much better with recommended pressure , but its so ruff and it bump steers and chatters a whole lot more. Gonna’ air back down tomorrow morning before i head to work.

Door sticker pressures on my Super Duty are 75psi front and 70psi rear. Since I bought the truck to tow my RV (85% of my mileage is towing) those are the pressures I run towing. But the ride is MUCH better, unloaded, (going for groceries - LOL) at lower pressures. I began by letting out 5psi, per tire, until I reached the most comfortable ride, until I reached 50psi per tire. I chalked the RF and LR and the contact patch was fine (as expected), then reset my TPMS via Forscan. Since I have an air compressor in my garage, airing up tires takes 10 minutes (airing down takes the same 10 minutes) Also, a good quality and ACCURATE pressure gauge is a must.

I have a 1000 mile trip coming up with a max load of maybe 600lbs in the bed. Can I drop 10 psi and not set off the TPMS?

im not sure if i would drop 10 with 600lbs in the back. Even aired up mine rides alot better with as little as 270ish lbs. in the bed. Yz250f, moto stand, gear, and a full jazz jug and it acurally rides pretty good. Mine trips at 12psi under the recomended pressure in the door jamb.

My TPMS sensors tripped at about 15psi from the sticker (55psi front and 60psi rear) I think the only way to know for sure is to progressively lower your pressures until the indicator lights. I confirmed mine with the dashboard indicator and a pressure gauge. Cold the pressures were within 2psi of each other (dash gauge and Auto Meter pressure gauge).

It is about tire pressure. If you’re going to air down, you need the torque of a diesel to overcome the increased rolling resistance of the underinflated tire. If you plan to run at recommended pressures, a gas engine is fine for you.

Yes, that diesel needs a lot of power while aired down to roll coal while mall crawling...

Ray, we might be neighbors. I'm in the same "town" on the east side off of Quebec.

75 on the front??? My F-350 calls for 60 front and 80 rear. Do you have a SRW? Agreed on getting a good gauge. All mine are digital now. They are within +/- 1 PSI of each other and within +/- 2 PSI of the TPMS sensors. The dial gauges were all over the place.

80% of the miles on my truck are towing. I keep my tires at 60/80. Even unloaded I don't mind the ride. I do have the Rancho 9000XL shocks, which made the ride better.
