that said...As a long-time solo RV'er, I often meet folks with RV fantasies. For those such as you, I sometimes recommend that they make a cardboard mockup of the unit they are considering (set it up in your living room?) and "live" in that for a week or two with your dogs. You can go outside, as you might with a real RV. You can go to the store. But you must really live in that confined space and see what it feels like. More expensive alternative is to rent a similar RV for a while.
Or maybe set up the smallest bathroom in your home to be your mock RV and stay in there for a few days. Will all of your daily stuff fit in there? What if you need item X? Where do you keep that? Where will the dogs' food bowls be? Where will you all sleep?
The RV lifestyle can be whatever you want - resorts or remote deserts or in between. You cannot realistically park it anywhere you want and live there. Some places are legal and free, but have time limits. Some places allow no camping at all. There is a whole underground world of "stealth camping" folks, which you can sometimes tap into on the internet. A shiny new expensive RV is not particularly stealthy.
Those are just a few thoughts to help you along your way. Fine tune that dream and then do it!
