For overall quality, I'd start with Newmar or Tiffin with Winnebago as a third option. With Winnebago, just pay attention to which product line it is as I think their lower end models are not even comparable to any gas Tiffin or Newmar. With your budget, I'd say that you may have to buy something a little older than a 2017....and if you find the right unit, save some money. We bought our 2012 Bay Star a couple of years ago and it was in superb condition, but it did need new tires.
Since you are considering a gas motor home, research the many modifications that are popular for improving the handling of the motor home and know what modifications have been made on any unit you are considering. There is a ton of information about popular mods such as the cheap handling fix (CHF), rear track bars, front stabilizers, Sumo springs. My Bay Star already had better rear tracking bar installed along with Sumo springs (front & rear). I found that getting the front end aligned, and adjusting tire pressure based on axle weight improved the handling. I had a Roadmaster stabilizer installed on the front, and that helped plus provides a little "insurance" in the event of a front tire blowout.
Good luck in your search! Take your time and find one that has good service records and will meet your needs.
