If you are completely new to RVing, I suggest you rent one for a week and I suspect you will learn a lot about things you like and don't like about a particular RV (or RVing in general).
These forums are great for helping with issues...and you will likely have issues as RVs are like homes undergoing constant earthquakes (while traveling). It helps a lot (in the bank account) if you are a do-it-yourself type and knows how to fix things. Otherwise, be advised that RV shops charge very high rates and they often have long delays to get to your rig (especially during the busy seasons).
