Should I buy a 22,500 gvwr or a 25,900 gvwr??

OK what size is the bed?

 

10K vs 12k axles?

 

What are you going to use the trailer for?

 

Need a little more detail, what will you be hauling? What are you pulling with?

 

You need to give more detail on the trailers.
What are the empty weights?

Does the 25,900 come with
20k (2x10)axels + 30k gooseneck or
24k (2x12) axels + regular gooseneck.


If the 25,900 one weighs 2k more due to a stronger frame, it's no cargo improvement.

However a stronger frame greatly extend the life if you are dragging equipment over dirt at construction/ pipeline / oil field sites. Frames are normally rated at either 14lb 19lb or 22lb per ft.

Also some trailers have higher capacity goosenecks to transfer more weight onto to the tow vehicle. This works for f450/f550's since they have greater load capacity in the rear. Kind of distribute the weigh a little more like a semi would.
Think of it this way:
20k trailer axel + 2.5k on the truck = 22,500 gross,
20k trailer axel + 5k on the truck = 25,000 gross (if your truck can handle it) other wise your limited to 22,500.

I'd wonder about the 25,900 if it has 2x12k axels, as that only leaves 1,900 for the truck. At full load you have may traction problems with such little weight on the rear axel of the truck. True ,you can move the load forward, but if you take the weight off the trailer tires, what's point of buying more expensive tires/parts.

 

very true, match your trailer to what your pulling it with, I have a Dodge 4500, and a PJ 40' that is only rated at 25k , I should've bought the 12k axles, but I got the trailer before the truck, was planning on pulling it with a F350.... good thing is, I am never overweight
