to the forum and to Keystone RVing. Here's hoping you find answers to all your questions and that your "new to you" fifth wheel will provide you years of enjoyable travelling.
You may get better response to your questions if you post them in the "repairs and maintenance" section. Some members who frequently answer questions and share information don't regularly check the "new members" section. There is also a "search" feature on the forum. Click on the search button located in the blue bar at the top of every forum webpage. You will find that most questions have already been askeed and a large amount of information is already available to you by searching.
Good luck finding answers and "happy repairing"
