Do they make a TT like this? Or am I asking the impossible?

Find a floorplan that you like with a dual pane option and custom order it. I was at the local RV show yesterday and a couple in the same trailer I was in were talking to a manufacturer rep asking about changing things they didnt like and there were very few limitations on what they were willing to change for very little $$. That would be the only way I wouldmthink you'll get the laundry list ofmitems you are looking for.
