Layton was a well known "brand name" RV of that era. I think the Toy Hauler in the Layton brand was called the Rampage. Layton was part of the Skyline Corp who also made Toy Haulers under the Skyline name too. But my guess is that it probably was built on the same line with different features & stickers. If it's in good shape it could be a good value, but you need to do a detailed inspection of any RV to make sure it hasn't had water leaks.
