Gooseneck Trailer for m7040

[JWR]

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???

I don't recall price differences (not a whole lot) but that is exactly the same thing I ran into with several sources -- in the 12K, 14K range the only difference was tires and wheels. The chassis was plenty stout enough for the larger number. The main diff was tire ratings. As I recall in the 16K model with Pequea the frame & all was the same but the axles were stronger.

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.

Ovrszd: As far as I can tell, his 10K load plus around 3.5K for the trailer itself (that is what my Pequea 1018 weighs) makes 13.5K total load. Whatever load is borne by the truck (say 1500lb) is subtracted from total load and leaves what is borne by the axles so he would only have 12K on the axles. With them rated at 7K each it looks to me like he has a reasonable 2K margin. Sorry, I just don't follow your 7K payload. (?)

Tires shouldnt make the difference in trailer rating.

A trailer with 7k axles......it dont matter if each tire can carry 3500#, or 13,500#......its still 7k axles.....and thus ~14k trailer.


A "16k trailer" would have to have axles rated for 7k IMO. Unless they are blurring the line even further and considering the 7k rating as a "sprung" weight rating. And as such, the weight of the axles, wheels, and tires technically dont count as weight being "carried" by the axles.

I was figuring the trailer at 5,500. Didn't realize those trailers were that light. I must have missed something. My 28+4 dual wheel weighs 6,800. Sorry.

Beats me??? I know there is some cheating going on with tongue weight. But in your example, I agree. You can put airplane tires on the trailer and it's still only got 7K axles. Beats me????

Usually the issue with tires is to make sure the tires can meet the axle rating.

 

[LD1]

Yep, tires don't determine axle capacity.....as long as.....they at least meet the axle rating. Which most oem trailers do.

Only time tires is ever an issue, is if axle is rated more than the tires as per the sidewall. And then you must derate

The gooseneck I've looked at ranged from 4200-7600.

Yeah, that's more like it.

JWR threw an apple in with our oranges. Just looked up his trailer. I believe it's a 20' bumper hitch.

[JWR]

True, mine is not a goose. I asked if he had to have a goose or not several posts back and don't recall the answer. Sorry for that confusion.

The 5th wheel versions do weigh more and most of that added weight is steel, forward and near the truck. My guess is that the added weight is readily supported inside the truck bed where it would not be on the rear tip of the truck. If that be true, the end result payload would be about the same for a given quoted capacity (e.g. a 12K GVW, whether goose or bumper pull), the truck would just bear more weight due to the type of trailer.

 

[Rustyiron]

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.

Could it be on the 16k trlr. that there is an 8k rated single wheel axle and the 17.5 tire offers a higher load rating and a larger brake drum with increased "swept area" for better braking capacity over the 14k trlr. ???

I guess it's possible. I've never heard of an 8K axle though. Usual jump is 7-10.

 

[Rustyiron]

That's what I thought as well, but it's been a while since Iv'e been axle or trailer shopping. An 8k single wheel axle would be nice to have as a lighter alternate to keeping 8 tires "in order":laughing:

 

[Xfaxman]

8K axles were optional ten years ago on my trailer, still available now: Equipment trailers from Delta Single Wheel Flatbeds

Probably should have ordered it with them.

Heaviest load that I weighed was 12,640, on the deck. 3440 on the gooseneck ball, 14,200 axles, 24,940 GCVW, 3/4 ton GMC.

From Sept. 2009.

 

[carlhwv]

That's a good load. How far did you carry it?

 

[Xfaxman]

That's a good load. How far did you carry it?

Hauled it home from Arkansas, about 430 miles.

The V417 that I have now is smaller and a little lighter, the same scales showed 12,660 on axles, 2,300 pounds on the ball. With the steel deck, the trailer weighs 5K.

I haul it backwards to protect the windshield.

For some reason the bumper-pull Pequea's run, as you say, 3.5,6 and then 10K axles. Their goosenecks offer more choices and have 6, 7, 8 and 10K axles. The 6,7 & 8K are all EZ-Lube brand axles. See http://www.pequea.com/images/stories/manuals/trailer/gooseneck/GooseneckTrailers_SS_lo.pdf I'm sure there are many good brands and choices.

 

[ovrszd]

Good stuff. Never heard of 8's. Thanks for the info.

I've heard good things about these guys and I see why. Another PA trailer manufacturing company. They might just be the best.

That would be a hard reputation to live up to!!!!

There are a Gazillion manufacturers of trailers. Many, many small town welding shops putting them out. My GN is a Neal brand, ever heard of them??? Central Kansas company.

Here's a thread link to an individual that might be truly building the "best" trailer out there.
