Even in NY they count the axles, NOT the tires...... but you are NOT allowed on the parkways....Interstate yes.

 

no. in ny they charge more for duallys.they consider four tires in the rear as two axles.i dont agree with it but they definitly charge more.also in n.y. (long island) we have parkways that are passenger car only and some allow commercial.it can get drivers from out of state confused.
i stand corected.i went on the ny state thruway site and they made changes recently.we went to lake george two summers ago and my friend nearly got arrested for arguing the fees with the toll colecter.on there web site they made abunch of changes in the laws.sorry.
motor parkway
william floyd parkway
robert moses causeway parkway...i think there is one in nassua county also.

 

The reason duallies are terrible in mud and snow it there is less weight per square inch applied to the surface. Same thing as narrow vs wide tires.

Besides stability the real world difference between srw and dual is the weight able to be placed on the rear axle. With load range E tires a dually can have around 10k and a srw can only be around 7k.

 

LIES God, its the same GCWR argument thats been going on forever. If you honestly believe a DRW can tow LESS whenthe rear axle is LARGER and STRONGER, just because it weighs MORE, then heaven help you. GCWR is a number Ford made up. It's based on the max weight Ford can put on paper from a legal perspective, then subtracts the weight of the truck. So, DER, the heavier truck would appear to tow less. But lets apply our God given common sense here. Remember, Macks tow more than Tundras. The bigger rear axle is NOT just dead weight added into the GCWR calc. Now lets start:

I'll ask you. Does a heavier trailer have a heavier pin weight or bumper weight than a lighter trailer? YES! Because it weighs MORE! So, the INCREASED bed capacity of the dually helps you tow MORE because you can put more weight on the pin/ball. If you know a way to safely tow a heavier trailer without loading up the tounge of it, please, share, because never in my life have a I seen a gooseneck trailer loaded to 15K# with a 500# ball weight.

So be a paper wuss, and never ever ever load your truck to more than the manual says. Trust you SRW to tow that 18.5K trailer, because that bigger axle on the DRW is nothing but dead weight, it doesn't help a bit, and going smaller only means that you can fill your water tank up, because that 250# would exceed the maximum for the dually. Break your axle shafts and wear out your brakes because a that extra 500# that 350 offers over the 250 doesn't matter at all.


But hey, if enough people say it on the internet, it must be true right?

 

If you follow the manufacture's recommended weighs like most of us do, than how is it a "lie"? According to Ford, the duallies can tow about 400 less than the same SRW truck. If you feel that you know better then them, then go for it, but don't call the rest of us liers

 

TexasTech - Actually, I agree with you as a common sense matter. I would definitely overload a DRW more than an SRW for much of the reasoning you provide. However, Ford's charts are the basis for most people's opinions.

 

well folks for what my experience is worth to you i'll share it. I'm towing a heavy 5er 16,000K plus with a short bed F250. So far I have three trips and about 1600 miles on it. Some in rainy windy weather and a trip over the mountains at Mount Eagle TN. Prior to that i towed a 12,500lb 5er all over the country with the same truck. I can for sure tell the difference. I'm not concerned that I'm hurting the truck and the pulling part is not much different than with the lighter trailer, but I would sure like more stability. To drive this rig I have to be very alert at all times. I've never been really uncomfortable but it's not really comfortable either. The interesting part is that the 5er has an extended pin box which does reduce the pin weight. On the scale the RAW was only 6300lbs. Only 300 more than my first 5er. I used to tow a lot of boats and I'm sure the 5er works the same way, the further back on the trailer the boat is, or with the 5er the longer the pin box is, the less weight there is on the back of the tow vehicle. Like using a lever. However, as the weight moves to the rear the trailer becomes less stable and it yaws (side to side motion). I've compensated some with airbags and 3415lb rated bridgstone tires. If it was simple I'd just get a dooley but ford has screwed up two diesel motors in a row so i have to find a really good 7.3. Besides, when we get where we're going i have to drive what i tow with so i try to tow with the smallest truck possible. Right now my plan is to try a set of Rickson 19.5inch wheels and commerical heavy duty tires. Once i get those on i may try using a shorter pin on the 5er which should calm it down a bit. If all that doesn't do the job i guess i'm lookin for a really good 7.3L dooley or a dodge. man it hurt to say that. I won't be home til march so i should have the ricksons on by april. I'll let you all know how it works out.

 

ive always wondered... are the 5th wheel trailers any more stable than the standard hitch trailers? and any less jerky?

 

In a word -Yes.

 

Any bed hitch is going to ride better than a bumper hitch, just because of where the weight is placed on the tow vehicle. Right over the rear axle, or ~3 ft behind it, what would you choose? Plus I personally prefer backing up a gooseneck over a bumper pull, buts just my weirdness.

 

right now.. probably a ball hitch since thats the only ones ive had experience with pulling... ive seen trucks with the goose necks.. but never really understand how they connect to the beds of the trucks and such.. our old 32 ft camper was a ball hitch one.. but it came with gas shock stabalizers to keep it from swaying.. but that was wrecked before i could ever really remember being in the car when it was towed...

 

Based on pulling a lot of boats, bumper and 7 years witha 5th wheel, there is no comparison. The 5th wheel is much much more stable with way less sway.

 

A gooseneck ball has a frame that runs between the frame members of the truck under the bed, and the ball locks to that frame with a pin, a lot like a reciever locks to a hitch under the bumper. There's just a hole through the bed, all the weight is on the frame. 5th wheel hitches mount to rails that mount to the frame.

 

thats was more what i was looking for.. ive seen them.. ive just never been able to look to see how the 5th wheels mounted to the bed... were either on trucks in motion.. or was too busy to stop and look at a truck in the parking lot.. (that and didnt want to look without the owners permission either.. didnt want them thinking i was trying to steal their truck)
