you will find manuals on this website, not a whole lot is different in these units or manuals from year to year and sizes... if you dont see exactly your trailer, pick the ones close to size and year should work for you. if you have specific problem or question, people been known to give detailed answers (much better than the manual) by asking the questions in approiate areas on this website.
