We were 4 yrs. 9 mos. full-time in our Reflection (GD) fifth wheel. Put 36,000 miles on it. We had a few issues, but all were with vendor supplied components like the frig. Grand Design really stepped up to the plate when it came to the few warranty issues and treated us more than fairly. We were happy enough that we ordered a new Solitude this winter and took delivery the end of February (great timing, eh?). The list of warranty issues included a cracked sewer line cap (probably from a rock in transit), and an auto-switching propane regulator with a non-functional indicator. Both were replaced by our dealership immediately. Though we're stuck in one place for a while now with the pandemic, we're really happy with the build quality and materials in the new Solitude and can't wait to hit the road again.
