I've taken off alot of Go-rhino's in the last 10 years, and they are heavily rusted after 5 years of service.
And most times you have to cut the bolt heads off with a torch.
On the other hand, Setina is not as bad. But lately the powered coating is on the thin side.
I have a PB400 on my F-150 and had to repaint the mounts after a year on. I used etching primer and oil base paint, and after 2 years I started seeing rust around the bolts. Probably due to the serrated nuts cutting into the mounts. But for ease of mounting and customer service, Setina is the way to go.
