Need help selecting generator

I am looking at purchasing a generator for power outage emergencies. Yes these are rare occasions, but since I switched from a motorhome to a travel trailer I miss having the convenience of just staying in the camper if the power is out.

I would like for the generator to be able to run my camper (jayco 33bhts) which has one 15k but a/c and all the normal stuff-it has 30amp service. I would also like to plug in 2 additional house refrigerators. I can of course run the RV fridge on propane if the load is too much.

It would be nice to have something relatively quiet, but since I don't plan on ever using this at a campground it's not a priority. We always camp with hookups.

I've been looking at units in the 7,000 to 10,000 watt range. Some have rv plugs directly on the unit and others do not-I assume there is an adapter if they do not?

These are some of the units I have looked at:
