I know very few RVers that got rid of their first RV for reliability or quality reasons. Most seem to be trading because they could not figure out what it was they needed for the way they were using it, or found something really annoying to them once they lived in it for a while. Same as people do with houses or apartments.
So do what you can, shopping, to try to work out what it is going to be like living in this thing. For RVs, that also includes setting it up, and getting to the places you want to be.
Saddest cases are the ones who need six months to a couple of years to figure out that they are not temperamentally suited to the lifestyle, or living together that closely, or that the experience doesn't match the dream. Particularly if it is only one person's dream.
