Our former 5th wheel was a SunnyBrook Titan toy hauler and we had to replace the roof after 4 years. The cost was around $7k for a. 40 foot roof. It was not damaged by Improper washing nor was it damaged by a tree branch. It just started coming up. We had it replaced and after 3 years, we again had the big bubble in front. This time, we just had it repaired. The loose part was pulled up and reglued. The repair lasted as long as we owned it. We would not get another rubber roof. We will look for other options. That 12 year warranty on the roof is just for the roofing material. If it is not defective but still rips and bubbles, the cost is on you.
