Most people here will say that Sunline is of some of the higher quality trailers/campers.
I have two myself and if I had more property (I live in a small city) I would collect a couple more.
The advantage of this forum is that the people will help as best they can, have Meet and Greets and stay on even after becoming a different make of trailer owner. This will happen as Sunline is no longer in business.
BTW. If you get a Sunline trailer or camper there is a couple Meet & Greets near us (I'm in CT). One in New Hampshire and one in the Adirondacks, so stay in touch.
