I've had a set of the Rhino Ramps for probably 6-7 years now. But mine are 8000 lbs capacity (Product 11903) and I don't think Rhino Ramps even produces this version anymore. Looks like they start out with 12000 lbs design & offer the 16,000 lbs version as the upgrade.

I've gotten considerable use from my set and hardly ever use the old metal ramps I have. Main difference - the angle of approach on the Rhino Ramps is shallow enough that today's cars can climb the ramp w/o rubbing. The Rhino Ramps are also much wider to accommodate today's low profile rubber. My old steel ramps had much steeper inclines (due to a higher overall lift) & I had to make a couple of transition pieces to enable the cars to go up the ramps. But the metal ramps have inclines that can be removed which is a plus for working in & around both front & back of tires. If I need that overall clearance, I get the steel ramps out. For changing oil by draining from the underside and/or replacing the steering stabilizer, the Rhino Ramps work great!
