Nope. I had my dealer install one on my 3300SK. It is a Carrier (nice unit) and they used the exisitng bedroom vent to create the drop and wired it to a seperate 30 amp disconnect in the lower storage area. It has its own 30 amp cable that can be connected via a cable feed thru in the bottom of the coach. Not had to use it yet though. So I think in order for the connections to be right, you'd need a 50amp hook up with a 30 amp seperate circuit or use adapters etc to get it done to use both units.
