Does any have or have used one of harbor freights cargo unloaders? I have watched some videos and they seem pretty effective. I would be mainly using it to unload leaves, sticks and landscape debris from clean up jobs. Right now I lay down a big tarp in my truck bed, fill it up with debris, then wrap it up and ratchet it down. It allows me to really get a lot of materials in there while also being able to drive safely with it loaded. Have any of you guys with one laid down a tarp on top of loader - if yes, do you have any problems with it? Please let me know your experiences and review on the product. Thanks everyone!
