Another vote for Grand Design, we have a 2017 Imagine 2600rb bumper-pull and love it. We had a smaller Imagine XLS before that and it was great as well. Like what has been mentioned, they're all built like a house of cards with small degrees of quality variance. From our research Grand Design was the best company to deal with after the sale so that's who we went with. If you're halfway handy you can work on them yourself, pretty easy to work on and there are tons of self-help DIY groups out there for them.
