Any advice on 7x14 14K dump trailer for my new truck?

[WM75Guy]

My haul vehicle is my 2024 GMC 3500HD 4WD with the 6.6 Duramax/ Allison 10 speed auto transmission. I started with a Big Tex 14GX 14' GN scissor lift with 2' sides, capacity of 7.2 yards. GVWR of 15,900#, 11,260# of cargo. I was hauling 6 yds of dry topsoil, probably slightly overloaded at 12,000#, but it fit in the bed level with the sides with room to spare. It wouldn't lift the load without raking some out with the tractor and shoveling some from the front to the back.

Traded it in on a Big Tex 14GT 14' bumper pull with 2' sides and telescopic ram. My model has the same capacity as the GN model. It is easier to hook up and lifts 6 yards without any problems. I did switch out to load range G trailer tires instead of the factory E rated tires as I haul heavy most of the time. Since I bought mine the newer 14TD model has been derated to a GVWR of 14,000# with a cargo capacity of 10,030#.

Find out the weight of the material per yard you plan on hauling. Unless you are planning on hauling light materials like trash or leaves the 4' sidewalls will add weight and decrease cargo capacity. The 6 yards of topsoil fits fine with 2' sides and lets the tarp fit flush with the sides. I use a large hoe to rake it level before rolling out the tarp.

Topsoil weights 2,000# - 2,800# per yard depending on how wet it is. Rock is heavier than dirt per yard. I would be limited to 4-5 yards of rock. For me telescopic ram is the only way to go now that they are available on small trailers. Mine has a 12-ton ram. No more shoveling material to get it to dump.

I like my single axle 4x4 dump truck, but I fully admit a dump trailer is an excellent choice. Cost-wise, Trailers are a joke to buy/own/insure/license/repair compared to owning a dump truck.

But I like having a dump truck. With each passing year, trailers are less enjoyable to hook/unhook. I can’t wait to get a hay truck and park the hay trailer

I picked up the trailer yesterday. It's in really good shape, so if it's not a great fit I can always resell for what I payed.

It was a seven hour round trip to pick it up. The 6.2 gasser got 16.2 mpg on the way down doing 75 most of the way. There were a few mountain passes, which it pulled just fine. 9.1 mpg on the way home towing the 4,500lb trailer. The 48gal tank sure was nice.

I have a dump trailer and it is very handy but for any large amount of material it is more economical to pay a full sized dump truck.(not even counting the time wasted). So unless the 140yards you need is very very close by to pick up I don’t think your looking at it the correct way.

I was quoted $2,500 to deliver 140 yards of gravel. They wouldn't use their big end dump truck to spread the gravel due to the camber of my road, so it was going to be delivered in a lot of trips using smaller trucks. Maybe I could do better at one of the other gravel yards, but this trailer is more about convenience than saving money. I also want to move around a lot of soil on my ranch and that gets old really quick with a .75 yard bucket, and 20-30min round trips.

Nice dump truck! I though about going that route, but decided against it for all the reasons you listed. I miss driving a "big rig" since I sold my motor home with a 450 Cummins.

You will not regret buying a dump trailer, they go hand in hand with a tractor/loader. I use mine more than any other trailer. They even work well for hauling large hay bales, that the customer can't unload, just dump them out. Pictures of your trailer??

(12) 3x3x8, 27,460 GCW or 1025 per bale.

Well even though the OP has bought his trailer I'll throw in my thoughts.
I've looked and thought about dump trailers and came to the conclusion the one I'd want is the deckover with the fold down sides so it could be loaded from the side with materials on pallets or anything using forks.

I can load and unload 2 pallets in my regular dump trailer. I could probably push 3 in but I couldn’t unload it without dragging it with a chain. It’s rare that I would want to haul more than 2 pallets at once because I have the big loads delivered and just have to pickup material if I run short. It’s also not much trouble to load a bundle of lumber in a regular dump trailer. You just set half the bundle on the end of the trailer and then reposition the lift and push it the rest of the way in. That’s the same way I load logs if I’m loading them with a skid steer instead of my excavator. I’m not in love with folding sides because they tend to be janky plus they limit you to short sides.

LouNY, That's a nice trailer and idea for sure!! - but how many loads of heavier stuff until the sides get tweaked enough so that the easy/quick load/unload feature disappears? I'm sure that will happen. The tailgate on my 1 ton dump bed has tweaked enough that it's no longer "easy" to open/close. It still functions but.....and just how heavy are those sides to swing back up after you drop them down? Looks like an ordeal in itself!

That's a serious setup, nice! 12 bales is a lot to haul at once in a 16ft trailer.

Here's a pic of the new truck and trailer. It's already getting put to good use moving stuff around the ranch.
