Purchased a 3220RL this spring and use it at a seasonal In Alberta Canada so don't pull it around. So far so good, been a wet summer with some serious heavy rains so very wet tested LOL. No issues and the midbunk and loft have been great for the two teen kids. Came from a Durango and quality seemed slightly better on this one but overall I think similar. The durango was a 2003 and also had no issues over the entire 17 years other then tires. My buddy purchased a new Jayco travel trailer and its been in the shop more then at the lake....they had to actually give him a loaner its been such a mess.
So so far we really have enjoyed the new Sandpiper.
