You may want to try and rent before you buy. Full timing is a HUGE jump especially with a child. What happens if you don't like the full timing lifestyle after a few months? You've spent a lot of money on something that heavily depreciates. Not trying to discourage you but I would recommend testing the waters before you dive in. As an analyst by trade I can tell you that all the research in the world won't clue you in to exactly what you want until you've actually spent some time in a few rigs. There are lots of places to rent class A, C or TT. May not be exactly what you want in terms of floorplan, but it will give you a sense of the lifestyle and will clue you into a lot of things you want or don't want in a unit. All that said, as others have stated floorplan is your largest consideration. Whether you pull it or drive it, floorplan is critical.
