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

Wayne,

I note that you said that dual pane windows are a must-have for any new trailer. Have you considered installing clear plastic sheeting over your windows to cut down on condensation?

I ask this because its is most likely that the floor plan you fall in love with won't come with the double-pane windows. Yes I know that some degree of customization can be ordered in trailers models that come with double panes, but I expect it maybe cheaper to go the plastic sheet route.
