Not a big deal to cut a hole in the roof for the new AC. You may want to add a separate 20 amp circuit so the new AC will run off the outlet in the post and not add to your 30A draw.
I don't know about the difficulty of cutting a hole and reinforcing around it to support a second AC, but I do agree you need a separate 20 amp circuit. That is by far the easiest way to accomplish what you are trying to do - other than going with a portable unit.
I have (had) a single AC unit on a 30amp trailer. I added a second unit in the bedroom (had a vent opening I could use) and ran a separate 20 amp circuit to power the second AC - I also added a wall plug on the circuit as well. It is located in the bedroom and allows a second electric heater in the winter or a hair dryer anytime. Very handy.
Here is a thread discussing adding a second ac on a 30 amp RV: http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/24889035/srt/pa/pging/1/page/1.cfm
