I put this Drywall Cart Dolly to the test for something a little different - moving heavy granite slabs for my outdoor BBQ build!! And it handled the job like a champ. The construction feels rock solid, and the expandable deck gave me plenty of room to balance the slabs. I even used it to cart the fridge, drawers etc to the backyard as well. The four swivel casters drove it very smooth, even on uneven patio surfaces with the pavers. I like the hooks for tiedowns, so you can lock things in. I wasn’t expecting it to handle that much weight, but it easily held up without any wobbling or tipping. When I was done, I folded it up and put it in the corner of the garage, easy peasy. If you’re looking for a heavy-duty cart that can tackle more than just drywall, this thing is a beast.
