Make sure your 30 to 50 dogbone passes power to BOTH legs of your 50amp feed - many coaches have one AC unit on one leg, and the other on the other. You need to make sure both legs are getting power. I'd test it before you get there to make sure.

I have never seen or heard of a 30 male to 50 female that did not connect the single hot on the 30 amp end to BOTH hots on the 50 amp end.
So that will not be a problem. As all have said, you will need to manage your electrical use, but the one roof A/C will be fine.
The only exception is that in some parks with only 30 amp service, the wiring is substandard, so be sure to check voltage (any outlet in the coach will do) when you turn large loads. 108 VAC is absolutely as low as you want to run your A/C.
