Maybe, you could remove them and have new ends installed or replace the lines. Your choice. Wear and tear is normal for anything. Depending on how things are used or abused is how long things last. There are many, many older CY's in service than your's, and are not having the problems you are. Maybe your just hard on your equipment. People jump these thing 10 feet in the air off roading and expect it to last. I have seen how the people treat their TH'ers going across the desert. As fast and hard as they can. Maybe you don't, I don't know. Maybe you should get a different coach...use it for 3 years...then report back here on how it's holding up. BTW, no matter who's coach you buy, it will still have the same lines and tanks as yours and the frames made by Lippert. Good luck.
