If you still have questions, just call the manager and schedule an appointment to have the questions answered and then take the trailer back to the dealer. Go through the trailer's features at home before you do this, and write down, make a list of all of your questions. Go over your list carefully, and you will find that many of the questions will be self explanatory. If you still have questions, just call the dealer's manager. Do not complain about the tech who did your walk through since he will possibly be the tech who will do your service/warranty work. The management will figure out that you received a fast shuffle on their own.
