Not a thing wrong with a older trailer. Ours is a 2002 as well. It is kept under a shelter and used quite a bit. I keep the roof sealed with new caulking and a couple of years ago I purchased the Dicor acrylic roof system from Camping World and refurbished the roof coating. I could see a few spots that were showing black mainly due to a custom fit RV cover I used to put on it particularly on the corners. I go over it meticulously each year. I do not have plans to buy another one for a while. Really if you keep one up like you should they will last you a long time. Enjoy.
