I'll throw out a different opinion.
I wouldn't take a big expensive studio-edit monitor on shoots. As soon as it leaves the studio, there are a hundred ways for it to get damaged. Dirty power, C-stand gets knocked over, vibration from traveling, etc.
I know people do it all the time. But unless I need a big studio type monitor to set up FX, or something of that nature that pays well enough to justify the risk, I say no. For most gigs a small lower cost monitor is risking a lot less, and is often more convenient to move around and place where it's needed.
