Also don't expect warranty problems to be fixed in a month, you would be lucky to get them to look at it within a month from what I hear of most RV service departments, not to mention the warranty approval and repair process. If getting initial build quality items fixed in a timely manner is important to you, then you might look into a brand that allows factory pickup (at an additional fee), Newmar is one that comes to mind, where you get a couple of days of time with a technician to go through the coach living in it at their on site rv park and come up with your punch list of issues, then some number of included hours of technician time to make the repairs before you are required to leave and schedule another service appointment.
Having said all this I would highly encourage you to take some time and do some looking at a few dealerships with motorhomes on hand, even if inventory is low due to the covid camping craze. My advice would be take a trip to Texas, go to PPL and then NIRVC in the Dallas, TX area (NIRVC also has a location in Nashville), followed by a 3 hour drive down to Motorhomes of Texas in Nacogdoches and see some coaches in person.
PPL to get a sampling of what is out there, this is a consignment dealer, that just shovels stuff out there, with no real prep, where you will likely see broken door knobs, torn fabric, etc., but also a variety of examples from many manufacturers. NIRVC where you will see both new and old coaches, and where you might consider buying, and Motorhomes of Texas to see well cleaned and staged used coaches, almost all used upper end and premium coaches connected to power with air conditioners running. The overall problem is thanks to covid inventory is going to be thin, dealers that had 40-50 coaches on the lot 2 years ago have 10 today.
