Have you ever RV'd before? do you have an idea of what you want? What do you have for a tow veh.? How big a trailer can it tow? If it were me I'd rent a few different size trailers and different floor plans to get an idea what I'd have to have in a floor plan ( island walk around bed, size of bath room and shower, food prep. area enough counter space to make a meal) and what I could live with. Then I'd make my 1st TT a used one because down the road your going to want something different after you've done it for awhile.
