Bigfoot makes two 25-footers for four-season use, both walk-around fore-aft queen, one with the bed in the rear, the other with the bed up front.
The front bed model has a little more kitchen counter space, back in the corner, but the table is located to be additional workspace.
As you get larger, there is more opportunity for kitchen space, but more often the space is used to accommodate more people. That's just what the market is buying, longer TTs to get more beds for families, fivers to get more living space for a couple.
When your requirements get that specific, and what you know you want is something quite different than what sells high volume, then you might consider custom building. I know who does that for fivers (New Horizons) but don't know about TTs. They used to do TTs in their 8-foot wide Summit line, was considering a custom build 10 years ago, but haven't seen TTs offered for several years.
None of these options are inexpensive, even a Lance or Bigfoot is a substantial step up in price from Pioneer.
