I did a lot of research. I made a spreadsheet of the brands I was interested in, then I went to each site and made a list of models with the floor plans I liked with the options I wanted. I narrowed it down to the Jayco Seismic 4250, Heartland 4150, and the Grand Design 376TH. After looking at them we decided the the Grand Design and will be taking delivery this weekend.
It took a lot of research, but I'm glad I did because I learned a lot about them. Good luck and take your time.
