All of our paperwork is in the trailer down in Corona--was planning on asking if they can look at the frame for us to see if there is a build date and/or builder listed. Spoke to the company in charge of the funds for the class action lawsuit to see if they could help...was told that even though there was an award made, that W/W went BK before any claims could be paid out. According to them, as of today there has not been a single penny paid. Also spoke to a woman at the "New Vehicle Resolution Unit" and was told that all attempts to resolve any issues with W/W have been met with silence.....After talking to the people at Warrior Lifestyles, (the ones repairing our trailer), build dates, frames, etc. don't seem to make a difference--they have repaired all different types of W/W trailers. I still firmly believe that my local dealer should have made me aware of the ongoing problems with the W/W company since we purchased the unit in early August 2007--while the class action lawsuit was still ongoing.
