DD,I'm not saying there welds aren't good,there beautiful,its just aluminum won't take the stress an airboat puts it through,I have seen over 2 dozen Dback aluminum boats get ripped to shreds because the engine stand let go,and yes they have a good warranty,but that does not bring someone back when they get killed.Why do you think Alumitech and American Airboats don't sell boats with aluminum riggs.I have personally watched with about a dozen others one of there engine stands flex over 2 inchs.I know it would not stand up to the abuse I put my boat through.That's why I went with stainless,they will all break that's a given its just that aluminum is more prone to it.
