Well 3 months has expired and no response from the factory, of course I haven't been persistent yet. I'm now to a point that I will have to be, the door will sag by 3" with just the weight of a person, no way will it support a 1000 per contact point. I have contacted lippert who explained that it was out of warranty, surprise there, I explained that I understood it was out of warranty, but there was a expected life of more than 18 months. They can sell me a n door for only 1500, which will turnout to be more in the end
