If you are just thinking of getting into RVing and have not done it before. I would say rent a few times and see if you really want to invest all that money into it. Then my 1st RV would be a used one in good shape, as you get into RV you will find out what you really want in floor plan etc. When you look at new ones and have never done it before or see floor plans you can become overwhelmed with it all. Like the queen size corner bed, but then someone has to climb over your sleeping partner to get up.
Or if you have kids making up the couch ever night for them to sleep, which means you have to go to bed at the same time because they now have the living room area. Etc. Lot to think about rent a few times different floor plans decide what you want or can live with.
