I suggest you begin researching more in depth and it doesn't hurt to visit a lot or two as well. Initially, try looking at PPL motorhomes to give you an idea of what is out there. In just a few short minutes I saw several different rigs that could probably meet your needs. Using this as a baseline you can then hit more lots with the knowledge in your back pocket.
When it comes to Class C's don't overlook some of the rentals that come up for sale. A patient buyer can get one pretty darn good deal.
I've said it before and I'll say it again. Set the budget then shop the floor plans adjust as necessary to find the one you really like. 5'er, A, B, or C is just a matter of what you want and can work with - the cost and floorplan are what you LIVE with.
