“Under hood generator”

We are shopping for a good used Class B van camper.
A number of them are being offered with what they call an “under the hood generator”, which I take to mean a second, larger alternator to provide AC power in the place of a traditional generator.
Can anyone who has used this system give me some info on how well this works to power appliances while you are driving?
Also, is this second alternator equipped with an electric clutch like the AC compressor so that it is not putting a load on the engine when it is not needed?
Thanks!
Bob
