View Full Version : Dump trailer question
12-24-2011, 01:53 AM
Im looking to buy a dump trailer and I'm wondering if my truck will be able to handle pulling it. I'm looking at a 7 x 12 dump trailer and my current work horse is a 2009 silverado 4x4 with a 6.0 vortec motor and 6 spd automatic allison transmission. The heaviest of weight it will be pulling will be when the trailer is full of mulch. about how many yards you think it can handle (trailer/truck). im hoping this trailer can hold 8 or more yards of mulch and the truck can handle towing it. I hope not buying a diesel isnt going to bite me in the arse. heres the trailer in question.

I hope your truck is a 3/4 ton pickup.I have a 7x14 with 2 ft sides and it will hold 10 yards of mulch.But I haul it with a f-350 dually.I had a buddy take mine one time and he had a 1/2 ton pick up and it was too much.You will be ok if you have a 3/4 ton pickup.the motor you have and tranny will be fine.Nice trailer by the way.
Have a Merry Christmas..............Al

I pull a 7 x 12 Brimar low profile dump with my 2003 Silverado 2500HD with the 6.0 just fine. I have two 2 x 10s for sideboards and it holds and hauls 8 yards of mulch just fine. So I think you'll be good...go for it.

My half ton with a 4.8 will handle pulling 8000lbs. With your motor/tranny you will be fine. 8 yards of mulch plus trailer might be a little heavy for the half ton suspension. May want to start with 6 yards and see how much spring you have left. I added one leaf to my half ton to help out.

Ohhhhh...he's got a half ton? I was thinking with the 6.0/Allison it must be the 3/4 ton. Still should do the job though.
12-24-2011, 02:25 PM
The truck is a 2500HD. This is my truck.

OK, not a problem for sure then.
I've had 3 yards of topsoil in mine before...not something I'd recommend.
Here's my rig...that's brush, not mulch in there but the only pic I could find that I hadn't posted yet.

Ive had my 2500 loaded with almost 6 yards of topsoil, as long as you dont have any big hills to go up it will handle 8-10 yards of mulch pretty easy.

thats a nice trailer darryl. if you take a look at the pic of the trailer i posted again doesnt it look like the tires are real close together as opposed to on your trailer? i asked the guy selling it about that and he told me he put new tires on it and those are the same size tires the trailer came with. said there is 3-4 inches of gap between them. hard to see that in the pics. so i hope hes right when i go to pick it up this monday. he tells me its heavy duty. 8 lug wheels and 12 ply tires. how much taller you think that trailer is than your lowboy?
12-24-2011, 04:03 PM
Yeah the tires do look pretty close together now that you mention it...they also look bigger than mine...those sidewalls look pretty tall. I love the low loading height on mine since I work solo a lot and it's only knee high...I can lift pretty heavy stuff that high. What I can't lift I can slide up the ramps usually. Mine is the single cylinder regular duty 10K gross. The heavy duty was a 12k (I think) and would have probably been a bit much for my truck. What's the gross on that one?
12-24-2011, 04:17 PM
I've pulled 5 tons. 14k total. With my 04 2500 hd reg cab as long as the weight is distributed and trailer brakes are on full power it's ok for back rds. I don't recommend doing it but u can if u had to!

heres the info on the trailer.
2008 dump trailer 12,000lb dump trailer equiptment doors with tie downs, duel doors barn doors, dump gate, new tires, twin hydraulic cylinders.
like i said, he told me he repaced the tires with what were the originals except instead of 10 ply he went to 12 ply. i asked if when loaded if the tires ever touched and thats when i was told is had 3+ inches between them and they never touch. said its a heavy duty trailer and attributed the big tires go along with the fact its heavy duty with 8 lugs rims. I'll know monday when i go to see it. im bringing cash so i hope its all he said it is. has bearing buddies, greasable fittings on everything,crank out tarp kit,adjustable height on coupler up front, tie down rings on it etc.. very good shape ive been told. The brand is Dump and go.

The 12k heavy duties are pretty heavy...probably 2 tons or so empty. I'd feel it was a bit overmatched for my truck...in fact it would be over my tow capacity at 12k... but you've got a bit more horse power and the Allison.

How did you get a allison with the 6.0. I thought you had to get the Dmax to get one of those.
You should be fine with 8-10 yards of mulch in there no problem. I have a 6x10 10k brimar that I pull with my 2500 6.0. The heaviest thing I have had in it was 3.5 yards of topsoil. I put it all over the axles and only went 20 miles on flat ground so it wasnt a problem. I had one really heavy wet load in the leaf box (appox 14 yards) that felt heavier but I think that it was just not as balanced. I have also hauled 5 yards of compost and 2 yards of stone without any problems. If you haul something heavy like topsoil or stone and put it over the axles, you shouldnt have any problems. I think a 6 or 7x12 trailer is the perfect size. Mine is good but a bit small to haul a machine and the 12' trailers seem to turn backing up a bit better.

i made a mistake with saying it has the allison. i was under the impression all 6 speeds were allison. after some reading i think i have the 6L80 hydramatic 6 speed trans and that the duramax is the only one with the allison. funny i just investigate this now.
the trucks tow rating is 10,700lbs. so if the trailer is 4000 lbs i can still town 6000lbs of mulch in it correct? not sure what mulch weighs exactly but id guess i could tow my desired 8 yards then and still be ok?
12-25-2011, 09:41 AM
Probably in the range of 600 to 800 pounds per yard on the mulch, depending on the mulch and moisture level.

I have two 6.0L w/ 6 speeds and I wouldn t hesitate to pull that trailer. I will say that the newer GM 3/4 tons seem lighter, but since one of mine is 3500HD with duallys I do most of my towing with that.
12-25-2011, 02:09 PM
i'm going for the trailer tomorrow ill let yas know how it goes.
12-26-2011, 07:38 PM
Brought the trailer home today. It towed very well and felt lighter than i expected. its almost 3400lbs empty. . I posted pics in the picture section.

My 2007 has the 6L90 6 speed automatic with grade braking and manual selection. Kick ass tranny for towing.
