How long do Rhino Ramps last?

[4WD]

Yeah … They're going to suffer from heat and darn sure UV … age is a tough one … but in risk assessments we consider both probability and consequences … cause and effects ? What is the failure mode ? The likelihood IMO is one ramp will partially collapse …

Do all Race Ramps have a removable rise ?

Has anyone had a failure with Rhino Ramps?
I have the Harbor Freight version...

I would really like to know; my life depends on it.
Thanks in advance.

Mine are 4 years old, stored outdoors, used when it's 20 degrees out, had them slip out when backing down, still no cracks yet.

If they're gonna fail they'll either break when you first pull up to it, or when you do something that moves the vehicle on the ramps. Once you're on and the weight stabilizes the ramps are no different than if you pulled up onto a brick or solid chunk of wood
