Rented trailer with no weight limit??

Is the trailer single or tandem axle?

 

Typical 28 ft pup freight trailer around 1000#/ft. So yeah 30k should be ok. Every trailer has weight limits.

 

If they say no weight limit, get it in writing and load that sucker up! Too many variables to guess accurately. I am sure at 28' it's a single axle which means you can have 20k lbs on the trailer axle, if a 3 axle truck is pulling it, it can have 34k up front. There is the issue of trailer empty weight, axle setup, truck weight, they are most likely gonna pull it as a set of doubles for any real distance, you wont know what the other trailer weighs for gross. When I pulled pneumatics, single axle day cab with lightweight bulk tank trailers, we were loading up to about 56k legally with a gross of about 79980 or so. That's roughly 28k per trailer. I'm gonna have to agree with about 25k in a van.

 

I never know my trailer weights, my manifest weights are pulled out of thin air
My Twin screw day cab with tandem 32’ lead and tandem 28’ pup
137,000 gross
Beer lead/meat pup

 

What are you loading that is 30k? The total contents of most 4 bedroom houses with a 2 car garbage. Barely come out to 30k and they fill up an entire 53 foot high cube trailer floor to ceiling

 

the pups I used to pull were rated for 20k of cargo

 

30,000 is 48 foot 53 foot trailer stuff.

I don't think you can stuff that much into a pup.

There should be a data plate near the front that will tell you what the trailer can carry in terms of gross weight.

I don't know what tractor you are towing with so, two axle or single axle? etc. I don't know if the trailer has one axle back there or two. (Probably one)

Then you need to break out the length, weight chart against your total axles, find the tare of both the tractor and trailer at a CAT scale weigh it. Then you will have a good idea of the gross you can be at. The difference will be what you can put into it.

Now in my time Ive hauled seacans at 20 foot boxes container with massive amounts of weight. And this is with a three axle tractor and a three axle chassis and STILL over weight, even with a 99K permit. Such a massive weight introduces serious driveablity problems.

30K? I'll probably split it and run two loads at 15K each. That way you will be relatively safe.
