New 5th wheel purchase. I think we have a lemon, need advice

I know you were anxious to get your new trailer, but did you and the dealers rep walk through the unit looking for problems prior to you accepting delivery?
Having documented those items then and having them fixed would have solved a lot of questions later, and yes I know this is a "if your foresight was as good as your hindsight" type of question but you didnt say how detailed your walk through was.
