I thought the Weight Police were blowing smoke all those times they suggested a dually. Well, hate to tell ya but there is some truth to what they say. Those extra two tires provide 2x the contact patch in the back and are LT tires, they are extremely stable.

Thanks!

Thanks for posting back...see so many who argue, argue, argue then
all of a sudden no more arguments...then see in their sig's that they
got a bigger truck, bigger SUV, moved from 'P' class tires to 'LT', etc, etc

Never to admit that was the case

Huge disservice to newbies reading thinking their advice was golden
to be mislead down the path... I get too many PMs asking about
some thing...one newbie so mad he wanted to sue someone here who kept
advising a half ton can do it, he's been doing it for a long time
and a valued contributor...but he seemed to either not care or didn't
understand that his was/is a HD half ton...a fake half ton but a
heavy half or a light 3/4...is advice lead to a newbie burning up his
diff towing a 'similar' trailer...but with a regular half ton...

Laws of physics this topic

More than 4 more sidewalls, more than 2x the contact patch but the biggie
is that the stance is wider (track)

Example is if some one pushed on my shoulders and my feet were together
I'd have a tough time managing to keep from tipping over or moving
over

If I had my feet wider apart and the same amount of push was imparted
on my shoulders, I'd not move much if at all.

PS...there is no such thing as the 'weight police', as there is no
policing on any open, free forum. 'Weight Police' is a deogatory
way of saying "I only want to hear what I want to hear"

Really no need to refer to something/someone saying something the
person asking is in disagreement...just wait a bit and tons and tons
of the 'sure you can', 'it is good for it', 'I have been doing that
for decades with no problems', etc will come along

Dually,

I towed my current TT with a F150 before. I thought that it was fine, but I just got through pulling my TT over 600 miles with my dually. Let me tell ya, there is a huge difference, I was worried about pulling through Atlanta during rush hour, we tried to plan around it, but we still managed to hit Atlanta at rush hour. The dually was exceptionally stable. Had a few times where I had to pass other vehicles and the dually was exceptionally stable. Had a situation where there were tractor trailers on both sides of me and I never felt out of control. If I can have anything to say about it, I will not pull a larger TT or Fiver without my dually again.

I thought the Weight Police were blowing smoke all those times they suggested a dually. Well, hate to tell ya but there is some truth to what they say. Those extra two tires provide 2x the contact patch in the back and are LT tires, they are extremely stable.

Thanks!

Jeremiah

The dually drivers seem to speak first and loudest on this subject. If you have been here for a few you woud have been able to guess all the answers in advance.

I have noticed that SRW's are common going down the road. I think if they were unstable the gov would be involved.

To me it is like the 4X4 decal - ya just got to have it.

Then I am not too sure of the way some simply express stability as a factor of the distance between the outboard side of two tires. No thought given to suspension and how wide the spring perches are on the axle. Give it some thought, stability surely has something to do with suspension also.

I am totally comfortable with my SRW and don't have to keep track of a big butt. But that is just me.

Now if you want to ask another question that you know the answer in advance just ask if you should get a diesel.

Bottom line is what you are confortable with and have something that is rated for the load. it is up to you.

The way I do my math I calculate that my truck has a stability issue of 0. If I get a dually I could have a truck that had 1/2 the stability issue that I presently have - which is still 0. If you need the duals for payload than you don't really have a lot of choice. As for blow out protection maybe you dually guys better start dueling up the front axle as well.


You missed my "big grin buddy". But just for you here

I only know two things:
1. I definitely LIKE my dually, and I enjoy driving it!
2. I got a true 11 to 12 MPG towing a fifth wheel at a GCW of 21,180 lbs at 65 MPH.
All the "Laws of Physics" and stability issues and all the rest are really meaningless. THOSE are the only real issues!

"There are only 2 kinds of men. Those who ride a Harley and those who wish they had a Harley..."
Now, THERE is another untrue aphorism! There actually ARE some men who do not ride a Harley, and really don't want a Harley. Personally, I would prefer a nice Gold Wing Trike. But then, if a smokin' deal on a good Harley Servicar came my way, perhaps... Nah, I'd rather have the Gold Wing. Or maybe a Valkyrie trike...
Actually, my motorcycle days are over. I don't think I will ever have another one!
I would rather have a good Karmann Ghia to tow behind the motorhome. Looking at the prices online, that sure ain't gonna happen!

Very true.

My GM dually was a much better hauler than my GM 3/4-ton. My Ford dually is a much better hauler than my Ford SRW.

I like all the various trucks I have owned, all makes and models, but a single rear wheel truck just can't touch a dually for load hauling ability. Only those who have owned both can truly know the difference.

This video shows just how much that bigger contact patch helps. Here is a big grin back to you
