There's a YouTuber on the Facebook putting up videos of his frame flex issues with a 2022 Keystone Avalanche. Apparently he had a visible crack on one side of the front deck, and when that side was taken apart, found a frame crack plus 10 or so broken welds. Keystone covered the cost, but did not approve opening up the other side to see what welds could be broken and other issues. I would think that Grand Design would have approved taking the whole front end apart. Keystone customer service is not good which is one reason I sold my Alpine!
