Installed a Big Sky gun rack in my p5 this week. It’s a very nice piece and I’m very happy with the fit and the way it holds my rifle. I had to cut about 4” off the tube so that it would fit on the p5 roof but it still had plenty of adjustment left if I needed to mount it someplace else. I chose to mount it between the tubes as my riffle will fit in the space and it maximizes the head room. I’m 6’0” and I have plenty of room even if it was dropped down below the ROPS. If you have a longer rifle I would suggest mounting it below the ROPS or on the back wall. One reason I decided on this rack was the way it clamped to the ROPS, it clamps to the tube instead of pushing out on the tubes.
