After towing two TT's and three FW's over many years and miles, I am absolutely convinced that the FW's are much more stable in crosswinds and while being passed by trucks. You will also find much more useable outside storage in the FW's. Once your truck is properly equipped to tow and STOP the combined weight, your miles towing the FW will be much more enjoyable. Some FW's even are equipped with hydraulic brakes which are electrically activated by a master cylinder in the coach. JMHO, but I believe they are very reliable.
The right floor plan for you is very important. As you know, many FW's also have the rear entertainment area you like. Some folks believe that I rear kitchen FW's bounce around more than a mid-kitchen FW.
If you must have the flat floor of a TT, you might look for a special hitch by "Pullrite" that swings in an arc under the towing vehicle. The advertised effect is similar to towing a FW in that the TT cannot exert much directional influence on the towing vehicle.
My disclaimer: I have not used the Pullrite hitch. I do not even know if it is still being sold but if I were to ever tow a TT again (which I won't), this is a hitch I would look for.
Best wishes for a fun and successful search. Drive safely.
