I know no one runs dumps on here. But i just got a new tarp for my dump and this tarp is quality. Not like the cheap one i had before that ripped. They do make flatbed tarps too or any size tarp for that matter. So if your looking for tarps try.
ds-sewing.com

 

Have used their tarps before, they are about an hour from me, good quality and price

 

I run a hopper trailer, so tarps are very important to my line of work. Its so nice to see a dump with a useable working tarp. Most of the dumps and rock trucks around here just have some rag like strips flapping in the wind. Another great place to get tarps, whether its on a grain trailer,rock trailer or skateboard tarps, is ECI, Edwards Canvas Inc. in Pauls Valley OK. They are just off I-35. They made a heavy 22 oz shurlock type tarp for my big trailer, and used canvas that matched the truck color for no extra $. A guy measured the trailer, then I watched about 8 or 9 tiny hispanic women sew it all up.

New Timpte came in last week, so now I'm back to a plain black Shur-Lok again.

 

I checked out the d.s. sewing site, they have a good selection to choose from on their tarps. But I noticed they use a lightweight tarp. I work for Fleet Discount Parts and our Vinyl Tarps start at 14oz and go up from there. We also carry replacement parts and full tarp system kits

 

If your located in Ontario DR Tarp located in New Liskeard Ontario makes anything you need. I love there -65 tarps on my Belt trailer awesome in the cold rolls right up without an issue.
