Utility trailer help needed – how much weight can I haul?

Forgive me if too off topic but I figure this was the right place to ask… I just bought an old Atwood utility trailer and the max load information has worn off the coupler so I have no idea what it can do.

I have to move this pile of veneer stones about 2 miles no freeway:

It’s got a 2″ or so square axle and one truss across where the axle is. Going to add a new 4×8 piece of plywood for flooring and have new wheels/tires on the way.

The rock pile is around 10′ x 1′ x 2.5′

How many trips do you guys think this will take? Thanks.

2, 3 to be safe. be sure you don’t get to much weight on the back end or the tongue. Be sure you have a good jack and go slow.

If you look at the tires, there will be a max load rating on the side of the tire.
This number times 2 will be your absolute max load, including the weight of the trailer.
Weigh a couple sticks of firewood to estimate how many sticks will add up to your max load.
Remember to balance your load evenly and stay well under your maximum weight.
That should give you a little more scientific method.

Thanks gents,

Tom, the new tires are 1300 lb rating each so I assume 2600lb – 600 lb trailer weight = 2k max load, unless axle can’t handle that.

I’m going to bring a scale and weigh an few stones to get an average, then do some quick math with a 10% margin of error. As Dutchboy suggested I’m now thinking 2-3 loads.

Will balance evenly. I’m guessing I’ll be able to cover the 4×8 floor up to around 1 foot tall on each run, but will know more after I weigh those rocks.

I don’t think I would load evenly. I would load more directly above the axel.

I think you’ll be surprised at how heavy those rocks are.

In the past when I’ve had to move heavy loads, I’ve considered the # of trips vs. the cost of renting a heavier trailer. If it saves me several trips and hours of my time, the $50 or so to rent is often appealing to me.

If going only 2 miles I would just load light and make a few more trips. It will also give you a break from loading.
