Bought 42 gallon tank 3 years ago, dump valve was broke after 1 year, they sent me a new one right away, just this week the front tires were both bad and went to the manufacturer as we were camping just 30 mins away and they gave me 2 new tires with rims and wouldn't accept payment.... great customer service
