Let's settle it amongst ourselves, once and forever.
Losing speed is NOT struggling. Neither is down-shifting.
Thinking otherwise is unrealistic expectations, which come from pre-conceived notions. Those come from 3 sources: what you read here, what you hear when talking to fellow pickup owners, and your own past experiences with quasi-similar vehicles hauling quasi-similar loads.
The way many of you type, it seems you expect a small gas V8, with economy gearing, in a 1/2 or 3/4 ton pickup, to tow a 20,000 pound trailer up a 7% grade at 85 mph, in overdrive, at half throttle.
How did any of you survive the '70s? We all did 3000 rpm just to do 55 mph. No turbo-diesels, no overdrives, just 454s and 460s with TH400s and C6s, turning 4.10:1 gears.
You guys don't seem to understand that the factories intend modern gassers to downshift and rev. That's most efficient overall.
With gassers, the overdrive ratios were never intended for towing up grades. It's impressive that the turbo-diesels often can, but don't let yourselves become jaded.
It's human nature to want more, to expect technology to give us dramatic improvements rapidly. But it leads to the common complaints that us tech gurus are becoming tired of seeing.

At least we know they never drove a truck for a living - that is why we are called gear jammers!

Your posts reminds me of something another member of a gun owners forum posted recently, "Only on an internet forum is a .38 Special not considered a man stopper". It will get the job done just fine just like the Ford 5.4, Chrysler 5.7, Ford 460, GM 454 will "Get Er Done".

My diesel only goes into overdrive on flat and slight grades when towing. If I am towing up a long grade, my tranny downshifts and either holds speed steady or gains a bit. I am not racing with a 40 plus length trailer or any for that matter. We do get use to the fact that our trucks empty move pretty quickly. I have no problem using the truck lane up a 7% grade for 5 miles. Keeps folks from getting pee'd off at me and its the right thing to do.

Watching the temp gauge raise beyond the 'normal' range

Watching the oil PSI fluctuate and drop a few. During and the killer...stays lower

Watching the MPH drop, even as you go all the way up to 100% throttle, even
as the tranny drops down one gear, then another

Watching exhaust start to show signs of oil burning (bluish smoke)

Seeing that the ATF color is getting darker and darker

Automatic hunting

Smelling diff fluid odor

Compression readings going down, down

Or that member of my church who always bragged how his Sequoia could
out tow others (F250 PSD, K2500 big blocks, etc). Knew when his wife
complained that we ruined his truck after that trip where the F250's
took off and figured it out, so ditto that. When he got stuck out
in the passing lane and had nothing left to 'have' to dive back in
to create a hazard to others. To when we saw smoke coming from underneath
his truck. To when the neighbor's kid, who is a ASE at a Toyota dealer
said that guy burned up his automatic and diff...that is struggling.



We all have different opinions on what 'struggling' means, or is. Above are
some of what I consider it to be

PS...my K3500 Suburban's 7.4L was also struggling on that trip with the church
members...

Sure it did jump up to +75MPH going up long inclines with about 80%
throttle and a few 100% throttle sessions. It could quickly get up
there to pass.

My oil PSI dropped a bit during and stayed down. Fluctuations coming back down
from Lake Tahoe said the Mobil synthetic ate it. Ditto the ATF.

Fresh charge too and only about 500 miles.

Changed it out and the oil PSI went back up to 45PSI at idle (hot) and over
75PSI above 1,200 RPMs (hot).

Also.. A higher reving engine doesn't mean things are going in a bad direction. Higher revs equates to faster moving fluids which also means more lubrication. That being said.. I did enjoy pulling my 27' TT with my 2500 CTD megacab over the 8cyl Ford Exploder and the fuel consumption was noticably diff. On the subject of handling, the improvement with the larger truck would not be related to the engine but rather the weight of the TV, the wheel base as well as the diff in frontal area exposed to the head/winds.

I might also add that in the smaller gasser the screaming of the engine did get annoying while on a cross country trip.

I used to be a "Gear Jammer" so I feel I can speak a bit on that subject. In most cases the revs are kept within a range for peak performance (Can't recall but typically 1300 - 2000 RPM??).. in a big truck once you drop down to 1300 or so you'd grab the lower gear (Which drops in at 1900 or so) untill no lower gears are available.. on the lowest gear (big load on a steep grade) sure you'd run loud and slow but you always keep it within the power band as if you could rev higher (Higher than 2000 and beyond) you'd likely grab the next gear if you felt you could hold it..

Excuse if my revs numbers are off for the big truck.. it's been a few years but I'm pretty sure I could shift it like a power ranger if I was back in the seat.. like riding a bike [emoticon]

I'm in this column also. The beauty of the 6 speeds is that you have 2 overdrives to use, but I haven't felt comfortable in 6th. I'm more interested in my RPM's than my speed. I like to stay around the 2K mark because that's where my torque, which is what moves my load, is at.

I agree with much of what you say. As long as you can maintain the speed limit or keeping up with other traffic, you're probably doing fine. Much LESS than that you may not be struggling but others on the road with you probably are (to maintain their cool waiting behind you) [emoticon] My diesel and my gasser both will maintain speed limits about the same but the diesel does it at 2,000 RPM and the gasser at about 4,000 sometimes.
