I'm in a similar situation. We have two children and currently are waiting for the twins. I agree that Montana is one of the most popular brands, but having surfed the Internet, I started thinking about buying the 2018 Keystone Cougar 367FLS. I have already taken the additional projects at work to earn extra money (fortunately, the guys from
https://isaccurate.com/korean-translation-services agreed to help me). Its price is about $50k that is reasonable for a fifth-wheel RV with a front living room. I should say, it is supposed to have enough space for a big family. Maybe this info will be useful for you, if you haven't made the purchase, of course.
