Hi and welcome!
Read forums and take notes. There are a bunch of systems that are somewhat like a house but most have a difference that there is a learning curve to RV'ing. And you will need to fix something on your brand-new expensive RV. Several somethings maybe.
When you find something that makes RV'ing easier get it. For instance a sewer hose wrench. Sure you have big man hands, but that wrench is nice to have.
