I think limiting yourself to one floor plan of model of one brand will continue to make this a difficult search for the near future. If you find 4-5 manufacturers with similar floor plans and specs and design your search accordingly, the above links will probably yield something.
Even then, it’s going to be a difficult search. Bumping up to a search for a B+ will yield much more favorable results in your budget and also get you more coach. Otherwise if you’re stuck on that model and you want something sooner than later, it looks like you’ll have to add at least $15k to your budget.
Here’s an example - I’m still playing with a search on RVTrader.com

Seems like more coach on a better chassis and can probably be had for the high end of your budget.
