Gooseneck Trailer for m7040

You can get a non-CDL class A license too. Not a bad thing at all. Just with my current setup I'm between 26-28k lbs.

Looking for a goose to hull my tractor between TN and MD. With implements and wet I'm just under 10K. The deck overs I've looked at appear a bit beefier than their between the wheel brethren. My bucket is 84" but don't see that as much of a problem. I like the axle placement of a between the wheel better than the other. Anyway, what has been the experience towing for those with mid sized tractors?

I don't understand this statement. Can you explain it?

I have had both types, but not at the same time and the axle placement was about the same, just from looking, didn't take measurements.

This deckover is a 14K, 22' long including the 4' popup dovetail, I bought it new, ten years ago:

What is your current setup Brett? I'm thinking I'll be below 26k, which is the limit I'm dealing with.

The placement of the axle on the dually seem to be a bit further back than the single wheel unit that I looked at. It might not be reality, as I didn't measure it. My concern is being able to get as most of my weight back over the trailer axle rather than in the bed and the truck axle, as my truck is single rear wheel. The good news from a call I just got off is that it looks like I'll have access to dual axle 28' 20k trailer to try before I buy. Trailer is a bit heavier than I would go, but it will give me a good idea how my truck pulls what a dual.

This is what I go down the road with now. Usually don't have the BB on there though. Trailer is 7700, tractor with loader and shredder was 11k, truck was around 7500-8000. When I went across the scales it was 27,580 or something like that. I'm in the process of selling my GN trailer and getting a larger one with bigger axles and a new truck that'll be rated to gross over 41k. With the new tractor and batwing coming I'll need it to be legal and under weights. I'm farm use so I don't have to deal with the cdl.

Looks like the truck is taking the weight good. If you didn't have the deck on the back how much further back would you move the tractor?

I lifted the truck and added a couple inches to the rear to reduce the squat. I almost always have something on the back of the tractor and will put the box blade right in front of the dovetail so I can flip the ramps up still. Always rides fine. I really like the tandem duals. Isn't such a pain if you have a blow up as you can get somewhere safe to change it due to the other 7 tires.

Especially 70mph with two Jeeps on passing a Semi on Interstate Hiway 35 with a line of cars behind you.

And try backing it up. I've only pulled a dual-dual once but maneuvering in reverse was awkward for me compared to a singe-dual and I'm not new to backing trailers. Might just have been the specific trailer I borrowed. :confused3:

Must have been. Mine backs great. Not sure how duals versus singles would alter backing characteristics.

With a GN the weight is between the axles, so the rear should not squat like it does with a pull behind. That is why it is important to properly install the hitch in front of the rear axle. You do need to keep the tongue weight below the truck's carrying capacity (GVW minus truck and content's weight).

I keep harping on this, but it is the voice of a lot of experience. It is easy to get the rig to carry the load by adding helper springs or air springs, and you can chip it up to make it go down the road faster, but none of those things help to make it stop properly. Whatever set up you end up with it is absolutely critical that the brakes are suitable for the load you are carrying. If you are not comfortable making a panic stop at highway speeds you need to make a change.

That is why tow ratings are given by the manufacturers. Most single rear wheel one ton 4x4's are rated to tow about 16,500 pounds with a GN setup. The 2017 Ford F-350 SRW is now rated at 20K, by far the heaviest in the class. A little on-line research will yield your truck's capacity.

Also, FYI: I recently realized that for 14k and 16k "rated" single wheel GN- all have two 7k axles. (or essentially all). Some manufacturers account for some of the load (2k) being carried by the truck's axles. So the trailers advertized as 14k and 16k have the same real-world capacity (assuming frame is structurally sufficient).

And that to me is false advertising. The trailer rating should be what the maximum weight rating of the tandem axle setup is. If they are factoring in the weight being carried by the tow vehicle they are misleading. As in your example.

The ones I looked at this week, the 16k units use 17.5 wheels to get the added capacity and the 14k use 16". I'm with you though. After a week of looking the ales are the weak link and I want as much of my load riding on those axles.

As with every type of "rating" weather it be loader lift capacities, truck tow capacities, or trailers.......there are so many variables.....so one must do their homework.

When I see a trailer listed as a 14k trailer......I take that to mean its just a 14k classification. And that the real world gross, or carrying capacity, may be different than simpley 14k on the money.

Kinda like 1/2 ton, 3/4 ton, and 1-ton class trucks.

Some half tons can carry more than 1000#, some less. Etc etc.

A 14k trailer is likely gonna have a pair of 7k axles as mentioned. Does this mean you can haul 14k? Or does that mean that 14k is the most the trailer is allowed to weight? The answer isnt simple.....so it depends.

To be "legal" typically, no single axle can weigh more than its rated for, as well as tires. So lets assume these 7k axles have tires that can handle at least 3500# ea.

Lets say this 14k trailer weighs 4k. If you put 2k on the pin with the load on.....the load must not exceed 12k....otherwise your axles will be over. Lets say you have a modern truck that can handle a 6k payload. And you want to put 6k on the tongue. You could easily load a 16k load on the trailer, and still not have more than 14k over the axles. And crossing a set of scales would show all being good. Is that smart to put that much weight on the pin on a 14k trailer.....probably not. But its not illegal.

My trailer was stickered "12-ton". Which makes it a 24k class trailer. It has 11,200# axles. But the vin plate is stickered 29,500 GVWR. And it originally weighed in the 5500# ballpark empty. So.....my interpretation of that is: you can actually put a 24k load on that trailer, bringing the trailers GVW up to 29.5k. Provided you have sufficient truck to put 7,100# on the pin to keep the axles under 11.2k ea.

So, IMO, there is alot more that goes into figuring a trailer capacity than just looking at weather its a 14k, 16k, 24k etc. Look at the axle ratings, and look at how much pin weight your truck can handle before the rear axle is over its rating. Add the axle capacities, and pin weight the truck can handle, then subtract the trailers weight. THATS the theoretical max you can load the trailer to.

I think there is some confusion here and there with these posts (load on your truck axles, etc.?) I am confident in saying that if it is primarily a 7040 you are hauling, any of the twin axle, single wheel per side per axle trailers, deckover model, with about a 7K lb rating of each axle will do just fine. Just no big deal. And you can put whatever fraction of the weight you choose on the trailer axles by locating your load on the trailer. Of course you want around 10% or so in tongue weight. 1000 to 1400lb is good and should not bother the truck at all.

That's so lame. So with identical axles/frame/hitch, etc., they increase the capacity rating by adding tires with higher load capacity??? That's so lame. What do they charge for this "heavier" trailer???

Yeah, I agree. Confusing to say the least. I prefer having too much trailer versus too little. My GN axles are 10K each. But I don't want to go around hauling 10K on each one all the time. I don't even like 7K car haulers. Too close to the capacity of the axles when hauling a heavy vehicle. Prefer 10K trailers for that purpose.

Using the OP's own description of his load, 10K, he'll either have to load the truck very heavily or overload the trailer axles to make your scenario work. Using your numbers and figuring 1,500 on the tongue, he's only got 7K of payload capacity.

In their defense, the price difference is about the difference in the price of the wheels/tires. I did see anything different...frame looked the same.

I was pretty sure I understood how to calculate weight and y'all have confirm d it for me. My number is not to exceed 26000 using axle totals and associated limits to keep in line with my license and insurance.

After listening and looking, I believe a well made single wheel double axle trailer would do fine for my application...I've got about 10k and the trailers are 4200...I've come to the conclusion that the idea of the extra tires and better breaks doing 500 miles trips seems worth the bit of additional weight. At least I get to try it before I buy it.
