Welcome to the forum keng.
We generally do think the Sunline quality is good and better than a lot of others however any unit you are considering buying needs to be cautiously looked at to make sure the previous owners didn't neglect things like the roof seams. A '95 would not be too old if the owner took care of regular maintainence items, particularly the roof.
