I don't know what other models have but on the WnP, and it is an OB, I'd have preferred they had used a tube of Sikaflex to mount it than they way the factory does it. At least then I could have more easily removed it and done it better with less cutting, welding and drilling. Anyway I was about to start a thread of the mods we've been up to and I'll post a pic of the way I did it and why, soon.
