My Funfinder is a 2008 and has been in the sun all but the last two years of its life. I purchased a cover for the RV and I kind of wish I had done it long ago. In my case, the cover works well. It takes about 15 minutes by myself to cover the 24ft trailer. I purchased a cover that was a bit too big but works well.
The roof is still in good shape and I wash it twice a year. I too would like to keep it for some more years. What can go wrong? It's a basic trailer that has no special bells or whistles. Living in Mexico there really isn't an RV repair option so any minor issues are handled by a plumber, electrician or recently a mechanic who cleaned and greased the brakes.
That said, it would be nice to think about a product that would be easy to apply when the time comes and will last for some time.
