1st timer need advice on buying used

Bubba - thanks for the clarification. I decided against the 28RL as it doesn't seem to meet our primary needs, which may be silly, but are that we need a floor plan that will accommodate a pack and play, and shower/tub combo and the bigger the kitchen/fridge/freezer the better as the Mrs likes to cook. The 28RL has only the dinette slide and stand-up shower....Back to the drawing board.
