I've got one on my 02 F-350. I like it, enabled me to mount 5 total gauges (3 overhead n 2 on the dash)
It blocks a little of the water temp on the right. The left side blocks the glowplug indicator, ck engine lite, and the bottom 1/3 of the fuel gauge plus low fuel lite. All can be seen by craning the neck a bit......
None of this has been a problem for me; I figure anyone who mounts up one of these knows enough to monitor the stuff.
The only hassle I had was putting the boost gauge on the left side. Had to cut a big hole in the side of the OEM bezel to fit the tubing and elbow. But it all worked out fine.
Good luck.

ps oh yeah dont get the LED gauges. They are bright as heck; no bueno at nite
you have to wire in a special dimmer switch to dim them.
