Congratulations and have many years of enjoyment with your new RV.
Did your dealer give you a PDI / orientation?
I don’t have a Palazzo and hopefully you will receive some good help soon.
Many motorhomes have an electrical outlet on one of the side walls. It will have a cover. Walk around your Palazzo and look for something about the size of any normal outlet.
I expect you have a hose connection that is labeled City Water. It may be in your wet bay. A Palazzo owner can confirm this.
