Yeah I've got the Harbor Freight ramp as well. I haven't had any issues with the construction, but if your truck is high, like at all, like a regular 4x4, it might not be long enough. The Harbor Freight ramp is significantly shorter than most that are more money. I used mine for a long time, still have it actually, but since putting the flatbed on my truck and hence raising the body about 5 inches or so, the incline on the ramp is too steep. I have to buy another one now.
