Third summer ownership of an 06 Hurricane 31D and I am very satisfied with the coach. The chassis is failure free and I have yet to have anything go wrong with the house side that caused anything more than a mental note to look into it next chance I get.
My thoughts are you have to take each owner and their prospective of a particular coach uniquely. I had the step motor fail the first year I owned the coach. Fixed it myself and didn't think much of it. Others may consider it a catastrophic failure and add it to the ever increasing list of problems. Also what I consider acceptable in terms of quality others may down check the entire manufacturing line. I like the light weight cabinets. Keeps the empty weight of the coach down so I can add more of my stuff to it.
Good luck with the upgrade and whichever manufacture you end up going with.
