Just my opinion, but if your going with an Evergreen RV product, I would get a model (which ever that might be) that uses the most compositec material. When I was looking that was the Everlite model which was a full copositec..no wood to rot construction. If you are concerned with feature you might have to find a 2012 Everlite model or older, because Evergreen is now using wood in their structure and you can not buy a 100% composite construction product from them.
Their support has been great. Dealers seem to be dropping out as far as promoting their products in this area. Dealers of Evergreen Products have been short lived it seems, NJ PA area. They are getting few and far between.
