Yes, FLOORPLAN!! How you plan to use your TT now may be different than when the family was along. Once you've determined which floorpan will work best look at all the manufacturers that offer what you want. I made a spreadsheet to do an apples-to-apples comparison of the 4 or 5 trailers that made our short list. In the end we went with the shortest & lightest TT that had all the elements we were looking for.
Take your time, happy shopping and good luck!
Oh, and a lot of RV salespeople have no idea how to handle an educated shopper..... :E
