Best constructed travel trailer

I enjoy this type of topic because it does open up a can of worms and you can find out a lot about different models. The overall best will be mentioned over and over. Right now I own a 2011 North Trail by Heartland manufacturing. Right now were having issues with the exterior walls delaminating and waiting to see if Heartland will do anything about it. So far they haven't but I am going to contact the VP next week. At this point would I buy another Heartland product, probably not. If they step up to the plate and help me out I might change my mind. I also just got done reading on their forum that several owners have had trouble with weak axles. A lot of the time the best depends whether it was built on a Monday or a Friday. Those built from tuesday thru Thursday are ok.
