Twice.

Vertical

Horizontal


Its a tight squeeze horizontally. I had to trim some of the cab stringers and I made a new mount with handholds because its so crammed in there. The main thing I'd say to be careful with is your depth. The 27" tube is much deeper and will bump the bezel if you don't set it back a bit.
You can't really see them in the pics (its actually not even installed in the second cab when I took them), but I just made bezels out of black foamboard. Since there isn't much depth from the bezel, I just wanted something flat to hide the bolts and monitor mount board.
I also put a 27" monitor in a 25" Golden Tee. I never really thought about it until this post, but it seems like kind of an affliction.
