No I have not. but it looks heavy to me.
Eight, 500' spools of 12 AWG is about 100 pounds.
I like this kind
I modified it by cutting part of the bigger axel off so that it will stand on one end for compact transit in the van. It stands just inside the rear door so I can pull wire off it in the van or take it out and wheel it to the job.
I do not feel like digging it out right now but here are a couple of it in the truck. Just imagine cutting off the 1" handle on the end with the wheels.
I like this rack because even when fully loaded I can get it in the truck by myself, I roll it up to the bumper, lean it onto the truck floor and then grab it from the bottom to tilt it up and push it into the truck. It also tucks into the corner of the van nicely.
