Find a model that has the floorplan and features you want AND is in your price range and go from there.
I purchased a Grand Design Reflection 27RL in 2017 based on the reviews stating how Grand Design stood behind their products. Well Grand Design got bought out by Winnebago and there is no customer service any longer. I have had many issues including AC replacement and total frame rust and got absolutely no help from Grand Design.
The majority have Lippert frames and I don't know of any that have dual entry doors.
I wish you well and safe travels
