40 mph meets the SAE J2087 spec. so according to those folks, slowing to 40's is not underpowered. It may be to you, or someone else, but it is not under powered per the engineers that design our tow rigs.

Ford didn't adhere to the SAE J2087 standards until 2015, so I'm not sure what a 1997 engine has to do with the price of tomatoes in Instanbul?

All I said => "I don't even like the thought of 7500lbs behind a 5.4l. " Much less 12,500lbs as mentioned to trigger my comment.

The one with 2.7 EcoBoost has 8,500 pound for towing and 2,250 pounds for payload. More than what I need since my TT has GVWR of 7650 pounds and about 800 pounds of tongue weight. That leaves 1,450 pounds for passengers, bicycles, etc.

Not really, you'll be hard pressed to find a truck with the listed max brochure payload of 2,250. The payload will be more like 1,200 to 1,800. XL and XLT models will be nearer the 1,800 # and the Lariat/platinum/etc. models will be nearer the lower number.

Technology does some pretty amazing things. An easy comparison is top-of-the-line computer from 6 years ago simply pales against a mid-level unit from today.

Thank you for all the great information. I spoke to my better half, she told me I need to keep my truck for now. :(

You do have a beautiful truck.. I really like the color.

Could be worse, you could have no truck right now.

Thanks!

My 5.4 pulled a 7700 lb GVWR TT (7000 ish loaded) with no problem.

I owned a 1997 and a 2008. Your definition of 'no problem' is different from mine.

I have no doubt that the new Ecoboost and the 5.0 V8 are well more advanced than my humble 235 hp 5.4 v8.

By no problem, I meant that I always got to where I wanted to go comfortably. On the interstate it would pull at 60 ish mph with very little issues. Really could pull much faster if I wanted to (I didn't).

Pulled some very steep grades at about 40 mph, but That was not a problem...

I would own another 2v 5.4, it was a very reliable motor, never gave me any problems other than a bad idler pulley and a clogged catalytic converter.

I am sorry you had two 5.4's that had problems. All of my modular Ford motors have been relatively problem free. (4.6, 5.4, and a 6.8)

Thanks!

Thank you for all the great information. I spoke to my better half, she told me I need to keep my truck for now. :(

Yup...technology has gotten much better. From lubrication, gaskets...to
metallurgy and more

Production processes hasn't stood still either

Then CAD/CAM...but that is where I've seen it fail. Today's designers
are very smart...but too many times rely on their canned software. Both
for design and simulation/testing/certification.

Nothing really new for these forced induction ICE's...other than direct
injection.

The 'marvel' folks espouse great enthusiasm is very similar to when the first
production turbos hit the market. Ford has done a good job from what I've
read up on, but for me, still waiting for them to start hitting the
used market and the biggie: rebuilds



Vehicles used to be considered used up at around 100K-150K and some
a bit longer.

Changed mainly due to that better material science and production science
mentioned above



My Silverado half ton 'can' haul over 3,000 lbs of firewood/wood pellets/etc
every year. About time to start checking the prices around here.
Some years has them deliver for free...so my Silverado gets a break...

6,200 GVWR and a 3,xxx RGAWR to boot.

'Can do it' vs doing it well...and know the risks. Replace the rear
axle bearings often and have lost count how many times. Know to check
as the cage deforms and many times allows a roller to come out if it

Too many here and other forums will take that and advise newbies or
anyone asking that they "can do it...I've been for years with no
issues". I'm not one of those and have a conscience for & of my advice

I've ditto'd that with my Suburban, but won't abuse my Sub often and
is why the Silverado is there...I keep my vehicles a looooooong time
AND...the Sub did a much better job of it and was able to take that
load out on the highway...where as the Silverado is kept to 25 MPH
on residential streets



Bottom line: chose what you like and then decide if you believe in
the OEM's ratings systems or not....

If not, then do whatever but know you have taken the OEMs off the
liability and warranty hook

If yes, then read up on those ratings systems work...and follow them
with actual weights for your plain math workups

I think the increased tow ratings for the newest half tons is a combination of marketing hype and technology advancement. I believe they should increase, just not to the levels they are at. JMHO.

Great testimony AZDesertRat! I must admit that in the back of my mind, I'm always thinking of this little engine that is working so hard...But, when those thoughts creep in, I look at the tach that is sitting around 1600rpm and the thought goes away.
