"Look at a Lance 1575 Tons of windows and openness! "
The 1575 is not 4-season.
But, that being said, I had a couple TrailManors. They were not 4-season, but I used them in the winter (pheasant season, Nov - Jan). We stayed warm with the furnace running 75% of the time.
I decided to get a 4-season, with other features the TrailManors didn't have. DW likes the added features. BUT, I could buy lots of propane to heat the non-4-season TrailManors, with the added cost of the new trailer!
If you can take the noise of the furnace, and can keep your tanks from freezing (could have, on the TrailManors), you may not need a 4-season trailer to stay comfortable. Save some money that way.
