I don't have any specific knowledge about destination trailers. I do know that Forest River has several offerings in that line. I do know a little about the Cedar Creek line of fifth wheel trailers. I know that most Cedar Creek owners and many Forest River people consider the Cedar Creek to be at the top of the 5th wheel line. I have toured the Cedar Creek factory a couple of times and the Cottages are on the same manufacturing line as the Cedar Creek and Silverback 5th wheels. They get the same manufacturing designs and care the the 5th wheels do. So it might be safe to assume they are at the top of the Forest River line of destination trailers. Can't speak for any other brands.
